Toa Payoh residents can compare grocery prices fairly by looking at a product’s cost per kilogram, litre, 100 grams, 100 millilitres or item instead of comparing the price printed in large type on two differently sized packs. Singapore’s Competition and Consumer Commission (CCS) and the Consumers Association of Singapore (CASE) expanded a supermarket unit-pricing pilot from 1 October 2026. The pilot displays standardised unit prices for selected categories at major chains and some online stores. Shoppers can also use CASE’s Price Kaki app to compare many everyday grocery and hawker-food prices.
The October 2026 expansion covers FairPrice, Sheng Siong, Prime Supermarket, Cold Storage and Giant, with Don Don Donki and RedMart participating under the published second stage. CCS reported that Price Kaki could compare more than 13,900 daily essentials at the time of its September 2026 announcement. These are national programme facts, not a claim that any specific Toa Payoh outlet has every listed product in stock today. Price, promotion and availability can change, so the best method is to compare equivalent products, account for storage and transport, and check the final checkout amount.
- **Unit price:** use a comparable unit—per kilogram, per 100 grams, per litre, per 100 millilitres or per item—as appropriate.
- **Price Kaki:** CASE’s comparison app covers many grocery and hawker categories and can help identify competitive offers.
- **2026 supermarket pilot:** expanded from October, with new product categories, operators and selected online outlets.
- **Real cost:** include travel, delivery, minimum-order requirements and the money tied up in large packs.
- **Value versus volume:** a large bargain pack is only a saving if the household can use it safely.
- **Freshness:** inspect product condition and storage life before buying discounted perishables.
- **Nutrition:** a lower price per gram is not automatically a healthier product.
- **Evidence:** keep a receipt and note the actual displayed terms when a shelf-price discrepancy occurs.
- **Household routine:** compare five to ten regularly bought essentials rather than spend every shopping trip researching hundreds of labels.
- **Useful outcome:** pay a sensible price for what the family genuinely needs, without overbuying or chasing misleading promotional claims.
Definition Lock: Shelf Price, Unit Price and Total Basket Cost
The shelf price is the price for one pack or item. A unit price is that amount divided by its measured quantity, using a standard unit such as a kilogram or litre. Basket cost is the combined price of what a household actually purchases, after applicable offers and fees.
These numbers answer different questions. A two-kilogram rice pack could cost less upfront than a four-kilogram pack, while the larger bag costs less per kilogram. An online basket may offer better unit prices but require delivery charges that increase the total.
This guide provides buying methods rather than live shop quotations. Real-time prices and stock require checking the actual retailer. An old screenshot, even from a legitimate app, is not proof of what a customer will pay this afternoon.
Why Toa Payoh Is a Good Example of Grocery Choice
The town includes neighbourhood markets, supermarkets, convenience outlets and shops around established residential areas. Residents do not all shop in the same places. The most convenient option depends on the block, route, work schedule and products needed.
An older person may prefer a nearby shop that is easy to reach with a trolley. A family might make a larger weekly supermarket visit. Someone with a full work schedule may use online delivery for heavy products.
Price comparison should respect these circumstances. A small saving at a distant outlet may be unattractive after a long trip. Good value includes money, time, convenience and whether the household can make use of the purchased products.
The September 2025 Pilot Was the Beginning
CCS and CASE began piloting standardised unit pricing with major supermarket operators in September 2025. The goal was to help customers compare goods that had different packaging sizes and to gather feedback about how labels worked.
The pilot was not a general rule fixing product prices. Retailers still set prices and promotions, while the labels provided a clearer way to compare them. Consumers were encouraged to give feedback about readability and usefulness.
The history matters because older shopping articles may describe only a limited set of stores and product categories. A 2025 screenshot may not show the wider second phase introduced in 2026.
October 2026 Brought a Wider Second Stage
The 28 September 2026 announcement described an expansion from 1 October covering more grocery categories, additional operators and online sales channels. The published retail partners include established supermarket chains and newer participating formats.
Shoppers can find labels in the relevant participating stores and, according to rollout arrangements, in selected online platforms. The detailed categories vary, so an absence of unit pricing on one product does not mean the entire programme has stopped.
Use CCS’s latest unit-pricing page when checking the coverage. For a particular purchase, the current shelf or online cart remains the final place to verify product and pricing details.
Which Supermarket Chains Participate?
The second-stage programme covers FairPrice, Sheng Siong, Prime Supermarket, Cold Storage and Giant, with Don Don Donki and RedMart also joining the initiative. The pilot’s participation schedule is not necessarily identical for every outlet or online platform.
A chain’s involvement does not establish that it offers the lowest price for every grocery category. The scheme provides information, not an award to one retailer.
Toa Payoh shoppers can use the unit labels at eligible branches, where available, and compare competing products. Do not recommend a particular shop as always cheapest without an actual dated basket comparison.
Price Kaki Has a Separate Role
CASE’s Price Kaki app helps users compare prices of everyday necessities and hawker food. The organisation has expanded product coverage over time, and its app may provide features for finding relevant outlets and following certain price changes.
A comparison app is different from a supermarket checkout. It does not reserve a product, guarantee availability or necessarily include every temporary discount.
Use it to shortlist sensible options. Then look at the retailer’s actual current price, membership conditions and final amount payable. An information tool becomes most useful when paired with real-world verification.
More Than 13,900 Essentials Is a Scale Indicator
CCS’s September 2026 announcement referred to more than 13,900 daily essentials available for unit-price comparison through Price Kaki. This demonstrates the app’s breadth but should not be interpreted as a guarantee of every brand and packaging variation.
Products are added, changed and discontinued over time. The correct item must be matched by size, variant and unit.
For a household, the most useful subset is often the repeat purchase list: cooking oil, rice, eggs, laundry detergent and other normal essentials. Consistency is more important than searching every product in the database.
How to Calculate a Simple Rice Unit Price
Consider an illustrative comparison, not a current retail quote. A two-kilogram pack costs S$8 and a four-kilogram pack costs S$14. The unit costs are S$4 and S$3.50 per kilogram respectively.
The larger bag has a lower price per kilogram but requires a higher immediate payment and more storage. If the family can finish it before quality deteriorates, the saving may be useful.
If the household lives in a small flat or uses little rice, the smaller pack may be more practical. A good decision combines the calculation with household use.
Compare Standard Units, Not Random Numbers
CCS describes standardised labels such as dollars per kilogram, per 100 grams, per litre and per 100 millilitres. Different products use the unit suited to their normal sale.
A label reading S$0.70 per 100 grams is not directly comparable with another reading S$5 per kilogram until the units are made consistent. An error here can make an expensive product look cheap.
Read the text beside the number. The calculation is straightforward, but only if the units and product quantities are correct.
Eggs Can Be Compared by Weight
A box containing twelve smaller eggs and one containing ten larger eggs are not necessarily comparable solely by count. Their total weight may differ substantially.
The unit-pricing pilot includes weight-based comparisons for eggs. This helps consumers distinguish pack quantity from usable weight, particularly when products are sold under different size categories.
However, a recipe may call for a particular number or size of eggs. Quantity, intended use and product quality remain important alongside the price per 100 grams.
Cooking Oil Is Often Compared by Volume
Oil bottles can have different volumes, promotional pack formats and types. A per-100-millilitre or per-litre calculation helps compare similar oils across those sizes.
Do not assume different oil varieties are functionally identical in cooking or nutrition. Match the product to the cooking method and dietary preferences.
A large oil container is not automatically better for a household that cooks infrequently. A product must be stored appropriately and used while it remains suitable to deliver real value.
Tissue and Paper Products Can Be Confusing
A large toilet-roll pack may contain different sheet counts, sheet sizes or ply thicknesses from a visually similar product. Packaging dimensions alone reveal little about total usable material.
Unit labels by 100 sheets or another consistent measure can help. Still, absorbency, softness and quality affect how much a family actually uses.
Compare like with like and avoid being misled by a package that appears bulky because of air or oversized wrapping. A careful label read is often more informative than the promotional banner.
Detergents May Have Different Concentrations
A concentrated detergent can require less liquid per wash than a diluted product. Comparing bottle volume alone may therefore favour the wrong option.
Read the manufacturer’s recommended dose and consider the price per suitable wash, when the information is available. Some products have different instructions for machine type or soil level.
Avoid using more detergent simply because a large container was inexpensive. Overdosing can waste money and may not improve cleaning. The goal is efficient use, not maximum volume poured.
Fresh Vegetables Require More Judgment
Leafy vegetables can be priced by kilogram, pack, bunch or item. Two packages may include different amounts of stalk, root or damaged material.
Compare suitable usable quantity, freshness and intended preparation. A larger discounted pack can be a poor bargain when much of it wilts before the household eats it.
Shoppers can plan a few meals around what they purchase rather than buy vegetables because the displayed unit cost is low. Preventing spoilage is an important part of affordability.
Fruit Should Be Bought for Actual Consumption
Fruit prices depend on variety, ripeness, size and packaging. A cheap bulk box may be appropriate for a large household but inconvenient for someone living alone.
Check condition and how quickly the fruit should be consumed. Some ripe produce is useful for immediate eating but unsuitable for storage across many days.
If half a box is discarded, the effective cost of the consumed fruit is much higher than the displayed price per kilogram. Responsible shopping measures what is actually used.
Meat and Seafood Add Cold-Storage Requirements
A bulk frozen-meat package may offer a lower unit price but require adequate freezer space, suitable portioning and safe handling. A small HDB refrigerator might not accommodate it conveniently.
Fresh and frozen products also differ in use and quality. Do not assume every cut can be substituted without changing the meal.
Follow SFA’s food-safety guidance for transport, storage and thawing. A price comparison is only worthwhile if the food remains safe from the market to the meal.
Baby Supplies Change Quickly
Diapers and other child supplies may be sold in a variety of pack sizes. A large pack can reduce cost per piece but become wasteful if a growing child moves to a different size.
For medically relevant infant products such as formula, suitability matters more than chasing a low unit price. Parents should follow appropriate health advice and not switch products solely on an app recommendation.
Track realistic consumption rather than buy several months of stock without a reason. A smaller pack can sometimes be the financially sensible choice.
‘Buy Two’ Promotions Are Not Always Savings
A promotion may lower the average cost per item when two packages are bought. But the second package costs money, occupies space and can expire.
Ask whether the household would have bought both without the offer. If the answer is no, the headline saving may not represent a useful financial benefit.
For shelf-stable essentials used regularly, multi-buy deals can be attractive. For produce or an unfamiliar product, a smaller ordinary purchase may reduce waste and risk.
Read Conditional Discounts Carefully
Retailers may offer reduced prices only for members, particular payment methods or qualifying minimum spends. A large advertised number may not apply to every customer.
Check the conditions before reaching the checkout. A paid membership or unwanted additional items can outweigh a small discount.
A promotion is useful when the household can satisfy its conditions naturally. Do not buy unnecessary products simply to reach a threshold that makes the receipt look discounted.
The Checkout Receipt Is Important
Occasionally a shelf label and scanned price may differ. Promotional periods can end or a display may be incorrect. A receipt provides a record of the actual charge.
Ask the retailer about the specific discrepancy, including the product, size and displayed offer. Keep a photograph of the sign where appropriate without obstructing customers.
Do not assume every mismatch is deliberate, but do not ignore a meaningful error. CASE provides information for unresolved consumer disputes. Accurate evidence helps all parties reach a fair outcome.
The Cheapest Single Item May Not Make the Cheapest Basket
A store can advertise an excellent rice price while other products cost more than at a competing outlet. Households normally purchase several things together.
Compare the cost of the actual basket, including typical quantities. This avoids making a special trip merely for a ‘loss leader’ while paying extra for everything else.
A focused repeat-purchase basket can reveal which shops fit the family’s normal needs. A permanent claim that one supermarket is cheapest across Toa Payoh would require much stronger and continuously updated evidence.
Travel Costs Change the Result
If a household saves S$2 on groceries but spends S$4 travelling to the alternative store, the apparent saving disappears. Time and physical effort can also matter.
A nearby outlet may be preferable for heavy goods, urgent purchases or older residents with limited mobility. A distant shop may work when the family already plans to visit that area.
Toa Payoh’s transport connectivity creates options, not an obligation to travel for every discount. Plan shopping around realistic routes and total cost.
Online Grocery Shopping Adds Delivery Fees
Online platforms may offer competitive shelf prices but charge delivery, service or other fees. Minimum basket thresholds can encourage additional spending.
Review the final checkout amount before comparing it with a physical visit. Delivery may still be good value when it saves a lengthy trip or helps someone who cannot carry heavy bags.
A fair comparison includes fees, required order size, substitutions and actual expected delivery. The displayed unit price is only one piece of the decision.
Substituted Products May Not Be Equivalent
An online retailer may offer a replacement when an ordered item is unavailable. The substitute could differ in volume, ingredients, brand or price.
Read the substitution policy and check what was actually delivered. A household managing allergies or a prescribed diet may need particular care.
A general description such as ‘similar milk’ does not prove the substitute meets every need. Shoppers should retain the ability to decline unsuitable alternatives under the actual service terms.
Wet Markets Use Different Pricing Practices
A Toa Payoh wet-market stall may sell by kilogram, bunch, piece or package, depending on the produce. It may not participate in the supermarket unit-pricing pilot.
Ask politely for the actual price and quantity, inspect condition and compare comparable products where practical. The relationship with a regular seller can also provide useful knowledge about freshness and intended cooking.
Do not assume a supermarket programme requires every independent stall to display the same label. Different sale environments have their own practices and applicable rules.
Hawker Food Is Another Comparison Category
Price Kaki includes hawker-food information. This can help consumers compare familiar meal categories or identify possible affordable options.
But the same dish name does not guarantee identical portion size, ingredients or nutrition. A lower price may reflect a smaller meal or different preparation.
Use the information as a reference and check the actual stall. For nutritional decisions and food safety, separate official guidance and the establishment’s current record are also relevant.
Nutrition Cannot Be Measured by Weight Alone
A product that costs less per kilogram is not necessarily more nutritious. It may contain different amounts of sugar, sodium, fibre or protein.
Read appropriate nutrition labels and consider dietary needs, especially for children, older adults or people managing health conditions. A lower price can be valuable without making nutrition irrelevant.
Good household budgeting considers affordability and suitable food choices together. The aim is an appropriate diet at sustainable cost rather than buying maximum food weight.
Food Safety Comes Before a Bargain
A cheap chilled product is not worth buying if its storage conditions are unsuitable or its packaging is damaged. Check relevant labels and handling instructions.
Food can become unsafe during travel home as well. A shopper who buys raw meat early in a long sequence of errands may need an appropriate cold-storage plan.
SFA’s advice applies regardless of retailer price. Preventing foodborne illness is more important than securing a discount.
Expiry Dates Require Attention
A shorter-dated product may be suitable when the household will use it promptly and safely. But bulk buying food close to the relevant date can create waste.
Read the actual ‘use by’ or other date markings and storage instructions. Avoid assuming all foods remain safe indefinitely because they smell normal.
The best value is a product consumed while suitable. An unused bargain in the rubbish bin represents wasted money and resources.
Compare Price per Meal Where Useful
Households often buy ingredients rather than finished meals. A practical budget can estimate the cost of a familiar recipe using actual quantities rather than treating every pack as one meal.
A large bag of rice supports many meals, while a small vegetable pack might be used in one dinner. Calculate realistically and include any leftovers that can be handled safely.
This method helps parents plan without creating an obsessive spreadsheet. A few regular recipes often provide enough information to guide an ordinary shopping list.
Prevent Duplicate Pantry Purchases
Before visiting a store, check rice, oil, noodles, canned goods and cleaning supplies already at home. Unnecessary duplicates can absorb cash and storage.
A short list can identify what is genuinely low and what can wait. This is especially helpful in smaller flats where cupboards may hide several partially used packets.
The cheapest product is sometimes one already owned. Organising the pantry can save money without downloading another app or searching for a promotional code.
Plan a Realistic Week of Meals
Choose meals that fit the family’s schedule and cooking ability. Write down the quantities needed, allowing for appropriate leftovers and occasional changes.
This creates a reason to buy particular produce rather than select items solely because they are on sale. It also helps prevent food waste.
A useful meal plan is flexible, not rigid. It should make shopping easier while preserving variety and family preferences.
Use a Small Repeat-Purchase Price List
Start with a handful of items that regularly affect the budget: perhaps rice, eggs, oil, milk, vegetables, detergent and paper goods.
Record normal package sizes and approximate prices at realistic nearby outlets. Review the list occasionally rather than monitor every price continuously.
The goal is familiarity with ordinary costs, so a promotional offer can be evaluated quickly. It is not necessary to turn household shopping into a full-time data collection project.
Price Kaki Is Most Valuable When Used Selectively
Use the app for items where meaningful price differences might influence the basket. Search the exact variant and pack size.
If the app produces a cheaper result at an inconvenient location, estimate travel and actual need before acting. Sometimes the sensible choice is to stay with the usual store.
Good comparison tools support decisions. They should not encourage a family to spend more time and money hunting discounts than the possible saving justifies.
Be Careful With Old App Screenshots
An old Price Kaki result may show a promotion that has ended. A photograph of a supermarket shelf may also omit the date, branch and membership conditions.
Return to the live retailer information for time-sensitive decisions. Do not forward an old image as proof that a Toa Payoh shop is currently overcharging.
Price literacy includes recognising when the evidence was collected and whether the products are actually identical.
Consumer Protection Is a Separate Safety Net
CASE provides assistance and resources for disputes over goods and services. A shopper who believes an advertised price was misleading can first seek clarification from the retailer.
Keep the receipt, relevant shelf information and correspondence. Clear facts help the retailer investigate and may support later formal action where appropriate.
Do not treat every price difference between competing supermarkets as unfair trading. Different stores can legitimately charge different amounts; the issue is whether the relevant consumer claims and transactions comply with applicable rules.
Shopping Apps Can Also Be Impersonated
Scammers may send messages that look like supermarket promotions or vouchers and request login, payment card or one-time-password information.
Open the genuine retailer or CASE app through a trusted source. Do not use a random chat link to obtain a supposed government grocery rebate.
A small sale discount is not worth sacrificing banking security. If a message creates unusual urgency or asks for sensitive credentials, stop and verify through official channels.
CDC Vouchers Are Not Price Kaki
CDC Vouchers, when available, are a separate government spending scheme with eligible merchants, conditions and expiry dates. Price Kaki compares prices and does not provide cash or a voucher balance.
A store accepting one type of voucher may have different prices from another retailer. Compare where practical, but follow the actual programme rules.
Do not confuse Climate Vouchers, CDC Vouchers and consumer comparison apps. Each serves a different purpose and should be entered separately in the household budget.
Large Households and Small Households Need Different Packs
A family with several children may use a large rice pack or bulk diapers quickly. A person living alone may prefer smaller amounts to avoid storage and spoilage.
Unit price helps both groups, but it cannot choose the right quantity for them. The consumption pattern matters.
A shopping guide should not shame residents for selecting a pack with a higher unit price when its overall cost and size better fit their circumstances.
Older Residents May Prefer Familiar Sellers
Shopping is also social and practical. A familiar vendor may offer manageable quantities and an accessible route for someone who finds long supermarket trips difficult.
Family members can introduce price comparison as an option, without taking over the person’s decisions or assuming they cannot understand digital tools.
An accessible nearby shop may have real value beyond the advertised unit price. Good advice respects the user’s health, confidence and priorities.
When Grocery Cost Is a Serious Hardship
A household facing difficulty buying essential food may need more than a better shopping strategy. MSF ComCare and appropriate community services can assess eligible needs.
Using Price Kaki may help a family make limited money go further, but it cannot solve every income shortage or medical expense.
Seek appropriate official assistance when basic needs are affected. Care and financial support are legitimate, and the household should not be blamed for failing to discover a cheaper brand.
A Four-Week Shopping Improvement Plan
In week one, list common purchases and compare their actual package quantities. In week two, learn the unit-price labels and use Price Kaki for suitable examples.
In week three, compare the total basket at two realistic shopping options, including transport or delivery. In week four, review actual spending and food discarded.
Keep the habits that work and discard unnecessary complexity. The best method is one the household can use calmly and repeatedly.
