The biggest savings on groceries in Singapore do not come from coupons. They come from three plain habits: write the shopping list in front of your open fridge, compare the unit price rather than the pack price, and throw less away. Once those are in place, add the extras that stack on top: house brands, the right discount day, CDC supermarket vouchers, loyalty points and your own bags.
Each habit is worth a few per cent. Stack them and the numbers become serious. As an illustration, 5% off a $150 weekly shop is $390 a year, and 10% is $780, without eating a single meal worse than you do now. Here is the system, and the arithmetic behind it.
Saving on groceries: quick facts
| Biggest single saving | Wasting less. The cheapest food is the food you already bought. |
| Easiest switch | House brands, on the staples you cannot tell apart |
| Discount days | FairPrice runs a senior or CHAS scheme on every weekday in 2026; other chains mostly on Tuesdays and Wednesdays |
| CDC supermarket vouchers | $150 from January 2026, to be spent by 31 December 2026; $250 from June 2026, to be spent by 31 December 2027 (per Singaporean household) |
| Bags | At least 5 cents each at large supermarkets |
| Time it takes | About 20 minutes a week, once the habit is set |
The WahLiao Verdict
| Cost | About 20 minutes a week and one honest look inside the fridge. |
| What you get | A repeatable weekly system, and the maths behind each step. |
| The alternative | Chasing promotions, which feels like saving and often isn’t. |
| Worth it for | Households spending $100 or more a week on groceries. |
| Skip it if | Your grocery bill is small and your time is expensive. Buy well, and stop there. |

First, sort the basket
WahLiao sorts all spending into pillars, fillers, buffers and hoarding, a method we set out in How to Control Spending. The grocery trolley is the easiest place to see it at work.
- Pillars are what you buy every week and always use: rice, eggs, milk, bread, vegetables, cooking oil, detergent. This is where savings compound, because a small saving repeats fifty-two times a year.
- Fillers are the pleasures: snacks, ice cream, the new sauce someone saw online. Budget for them honestly; do not pretend they are pillars.
- Buffers are the sensible reserve: a few tins, a spare bag of rice, frozen backups for the nights nobody can face the stove.
- Hoarding is a buffer that has lost its reason, usually after a promotion. Four bottles of fish sauce is not a buffer. It is a museum.
The steps below work mostly on pillars. That is not because pleasure is wasteful. It is because pillars are where the money is.
Step 1: Check the fridge before the shelf
Food thrown away is the most expensive item in any trolley, because you paid full price for none of the benefit. It hides in plain sight: the spinach bought for a healthier week, the second bottle of soy sauce, the chicken meant for a dinner that became a hawker centre.
So write the list at home, with the fridge door open and the pantry in view. Plan the week’s dinners loosely, then list only what those meals need that you do not already have. When you unpack, put new food behind old, so the older pack gets eaten first. This single habit tends to save more than every coupon you will ever clip, and it costs ten minutes.
Step 2: Read the unit price, not the pack price
A pack price tells you what you pay. A unit price tells you what you get. Many shelf labels in Singapore show a price per 100 grams, per litre or per piece; where one does not, divide.
Take an illustration, with invented prices. A 2 kg bag of rice at $4.80 costs 24 cents per 100 g. A 500 g bag at $1.30 costs 26 cents. The bigger bag wins, as you would expect. Now put the small bag on a “2 for $2.20” promotion: it falls to 22 cents, and the small bag wins. Size is a clue. The unit price is the answer.
Step 3: Try the house brand, one category at a time
Every large chain now sells its own labels. FairPrice has its Housebrand range, and Sheng Siong’s own brands run to 28 labels and more than 2,000 products. House brands usually cost less because the supermarket spends less on advertising and controls the supply.
Do not switch your whole trolley in one week and then hate everything. Switch one category at a time, starting with the ones where brand matters least to you: paper towels, cling film, cleaning products, plain rice, tinned tomatoes. If nobody at home notices, keep the switch. If someone notices, go back and do not argue. The saving on one detergent is not worth a household mutiny.
Step 4: Shop on the right day
If a senior in your household shops anyway, let them shop on their day. At FairPrice in 2026 there is a scheme on every weekday: 3% for Pioneer Generation cardholders on Monday, 2% for seniors aged 60 and above on Tuesday, 3% for Pioneer and Merdeka Generation cardholders on Wednesday, and 3% for CHAS Blue and CHAS Orange cardholders on Thursday and Friday. Other chains run 3% to 4% senior days, mostly on Tuesdays and Wednesdays. The full calendar, caps and rules are in senior citizen discounts at Singapore supermarkets, day by day.
The discount belongs to the senior, who must be present. It is not a coupon to borrow. Used honestly, it is still worth up to $6 a day at 3%.
Step 5: Spend CDC supermarket vouchers on pillars
Every Singaporean household received two tranches of CDC vouchers in 2026. The January tranche of $300 included $150 for supermarkets, valid until 31 December 2026. The June tranche of $500, brought forward from January 2027 to help households with rising costs, included $250 for supermarkets, which can be spent until 31 December 2027. Claim them at go.gov.sg/cdcv.
The supermarket portion works at Ang Mo Supermarket, Cold Storage, Giant, HAO Mart, NTUC FairPrice, Prime Supermarket, Sheng Siong and U Stars. Don Don Donki is not on the list.
Two pieces of advice. First, spend vouchers on pillars you would buy anyway, rice, oil, milk, detergent, so they replace cash rather than invite extra fillers; a voucher spent on a treat you would not otherwise buy saves nothing. Second, if you still hold January vouchers, they expire on 31 December 2026, so use those before the June ones. Watch, too, for return-voucher offers around voucher launches: in June 2026 FairPrice gave a $6 return voucher for every $60 spent with CDC supermarket vouchers in a single receipt, for a limited window.
Step 6: Use promotions; do not obey them
A promotion is a controlled disturbance, designed to change what you were going to do. Sometimes that works in your favour. Before you take one, ask three questions.
- Is it a pillar? A discount on something you always buy is a saving. A discount on something you never buy is a purchase.
- Is the unit price actually lower? “Buy 2” deals are sometimes no cheaper per gram than the large pack beside them.
- Will you use it before its date, and do you have room? If not, the deal becomes waste with a receipt.
Three yeses, take it. One no, walk on. The supermarket will be running another promotion next week. It always is.
Step 7: Split the shop by channel
Singapore households rarely buy everything in one place, and the smart ones do it on purpose. Buy fresh vegetables, fish and meat where freshness and price meet for you, often the wet market or a supermarket with strong fresh counters (our history of Singapore’s wet markets explains why they still earn their place). Buy dry goods and household staples at the supermarket where your basket is cheapest. Have heavy things delivered.
Online, the arithmetic is the delivery fee and any service fee. A small order with both added is usually the most expensive way to buy groceries in Singapore. Batch your heavy pillars into one planned order that clears the free-delivery threshold, and never top it up with fillers just to cross the line.
Step 8: Collect what you are owed
If you are an NTUC Union or Link member, FairPrice gives Linkpoints on purchases in store and online, and they are redeemable against later shopping. Scan every time; unclaimed points are a small annual donation to nobody.
A credit card that rewards supermarket spending can add a little more, but only if you pay the bill in full each month. Grocery rewards of a few per cent vanish the moment a single month’s interest is charged.
Step 9: Bring bags, and keep a month of receipts
Large supermarkets charge at least 5 cents per carrier bag. It is small, and entirely avoidable; the details are in the 5-cent bag charge, explained.
Then keep every grocery receipt for one month. At the end, circle what you threw away, what you bought twice, and the three pillars that cost you most. That single page will tell you more about your household than any budgeting app, and it gives you a baseline to compare against the WahLiao Price Index.
What not to do
- Do not cross the island to save 50 cents. Your time and your fare have prices too.
- Do not buy near-date food in bulk. A short runway and a big pack is how bargains become bin bags.
- Do not treat vouchers as free money. They are money. Spend them like it.
- Do not chase every promotion. The shopper who saves most is the one who needed the least.
The weekly system on one screen
| When | What you do | Time |
|---|---|---|
| The night before | Open the fridge, plan dinners loosely, write the list of what is missing | 10 minutes |
| At the shelf | Read unit prices; try one house brand; apply the three-question promotion test | No extra time |
| At the checkout | Right day for any senior discount; CDC vouchers on pillars; scan for points; own bags | 1 minute |
| At home | New food behind old; freeze what will not be eaten in time | 5 minutes |
| Once a month | Review the receipts: what was wasted, doubled and dearest | 10 minutes |
Frequently asked questions
What is the cheapest supermarket in Singapore?
It depends on your basket. Each chain is cheaper on some items and dearer on others, and promotions change the answer weekly. The honest method is to price your own pillars at the two supermarkets nearest you for a month. WahLiao prices a fixed basket for the Price Index, and our cheapest-supermarket verdict will rest on those receipts.
When do CDC supermarket vouchers expire in 2026?
The January 2026 vouchers expire on 31 December 2026. The June 2026 vouchers can be claimed and spent until 31 December 2027. Use the older ones first.
Are supermarket house brands lower quality?
Not necessarily. Quality varies from product to product, as it does between big brands. The only reliable test is your own household, one category at a time.
Is buying in bulk cheaper in Singapore?
Per unit, often. In practice, only if you have space to store it and will use it before its date. Check the unit price, then check the cupboard.
Is online grocery shopping cheaper than going to the supermarket?
It can be, if you batch orders above the free-delivery threshold and avoid impulse buys. Small orders with delivery and service fees added are usually the most expensive way to buy groceries.
