π What is changing?
The first pilot ran from September–December 2025 at FairPrice, Sheng Siong, Prime, Cold Storage and Giant. CCS and CASE said consumer feedback was encouraging, particularly for comparing different brands and pack sizes. (CCCS)
The second phase is substantially broader:
| Change | Previous pilot | Expanded pilot |
|---|---|---|
| Supermarket operators | 5 | 7 |
| Don Don Donki | ❌ | ✅ |
| RedMart | ❌ | ✅ |
| Online shopping | ❌ | ✅ |
| Product range | More limited | 40 grocery categories |
| Duration | Trial | 8 weeks per operator |
From 1 October, FairPrice, Sheng Siong, Prime, Don Don Donki and RedMart start. Cold Storage and Giant follow from 1 November. (CCCS)
What exactly is "unit pricing"?
Instead of just:
Rice — $8.90
you might see:
Rice — $8.90
$4.45/kg
Or:
Cooking oil — $6.90
$0.69/100ml
The idea is that you don't have to calculate whether a 1.5kg $7.50 pack is actually cheaper than a 2kg $9.20 pack.
CCS specifies standard units depending on the product — for example, eggs can be priced per 100g, cooking oil per 100ml and leafy vegetables per item. (CCCS)
π₯ The expansion is quite significant
The pilot now covers more everyday products including:
Rice, flour, bread, noodles and pasta
Meat, poultry and seafood
Milk, cheese and eggs
Cooking oil and butter
Fruits and vegetables
Sugar, spreads and preserves
Coffee and tea
Soft drinks and other beverages
Detergents, tissue, shower products and diapers
Snacks and biscuits
Soups, sauces, spices and salt
So this isn't merely a rice/oil/egg experiment anymore. It covers a much larger proportion of a normal family's grocery basket. (CCCS)
π± The interesting part: RedMart
This is probably the most useful change for online shoppers.
RedMart and Sheng Siong will display unit prices online from 1 October. Other supermarket operators are expected to progressively introduce online unit pricing. (CCCS)
That means online shoppers should eventually be able to compare something like:
Brand A: $5.90 / 500g → $1.18/100g
Brand B: $8.90 / 1kg → $0.89/100g
without doing the maths themselves.
For people who frequently shop groceries online, this could actually be more useful than the physical-store labels.
π¬ What are Singaporeans saying?
There's an important caveat here: the September 2026 expansion is extremely new, so I found much more substantive discussion around the original 2025 pilot than around the new ST article itself. Searches across Reddit, HardwareZone and indexed social results haven't produced a large body of meaningful discussion specifically about the 28 September announcement.
The existing discussion, however, is remarkably consistent.
Reddit: generally positive
The 2025 r/singapore discussion received strong engagement, with many commenters welcoming the idea.
One recurring sentiment was essentially:
finally, shoppers don't need to calculate price per gram/100g themselves.
Others specifically highlighted shrinkflation and imported products with awkward package sizes as areas where unit pricing is useful. (Reddit)
There was also a particularly practical observation: unit pricing can expose situations where a "30% off" smaller pack is still more expensive per gram than a larger pack that isn't on promotion. (Reddit)
HardwareZone: more sceptical about supermarket pricing practices
HardwareZone discussions aren't specifically about this new announcement, but they show why unit pricing could resonate with some shoppers.
There are longstanding complaints about:
confusing shelf labels
prices not matching the product
electronic price tags not displaying information
consumers needing to check prices through supermarket apps
significant price differences between supermarkets.
One HardwareZone thread, for example, discusses an instance where an electronic price tag allegedly wasn't displaying a price after the product price had increased. Other users chimed in with their own experiences of supermarket price-tag problems. (HardwareZone Forums)
Another HWZ discussion illustrates the broader Singaporean habit of actively comparing supermarket prices across chains, down to individual products. (HardwareZone Forums)
So the underlying consumer behaviour already exists; unit pricing potentially makes that comparison much easier.
π What people seem to like
Across the discussions surrounding the pilot, the strongest practical benefits are:
1. Makes promotions easier to judge
"20% off" doesn't necessarily mean better value.
Unit pricing lets you ignore the marketing headline and compare the actual cost.
2. Helps detect shrinkflation
If a product goes from:
500g → 450g
while remaining $5, the change in unit price becomes obvious.
This was specifically mentioned in the earlier discussions. (Reddit)
3. Makes house-brand comparisons easier
Instead of:
FairPrice brand $4.50
Brand X $5.80
you can compare the actual $/100g.
4. Particularly useful for families
Large families buying rice, milk, cereal, snacks, detergent, diapers, sauces etc. have many situations where pack sizes differ.
5. RedMart is potentially a big deal
Online grocery shopping normally makes this comparison surprisingly annoying because different products are presented in different sizes.
The new online unit pricing should make RedMart's search results considerably more useful for price comparison.
⚠️ But unit pricing doesn't automatically mean "cheapest"
This is the important distinction.
A unit price tells you:
How much you're paying per unit.
It doesn't tell you:
Whether you actually need the product.
For example:
1kg cereal — $10/kg
may be better value than:
500g cereal — $6/kg
but you're still spending $6 versus $10.
Likewise, a 2-for-$10 promotion might look attractive, but if you only need one, the unit price doesn't necessarily make the promotion economically better for your household.
And unit price doesn't account for:
taste
quality
ingredients
country of origin
brand preference
freshness
wastage
loyalty points
cashback
vouchers
supermarket-specific promotions.
That's particularly relevant in Singapore because FairPrice/RedMart/Donki/etc. promotions, vouchers and cashback can materially change the effective price.
π§ My read of the significance
I think the RedMart component is actually more interesting than the Don Don Donki component.
Physical supermarkets already allow you to pick up two products and calculate the difference. Online grocery shopping makes this much harder.
The progression is effectively:
2022 → Price Kaki
↓
2025 → physical supermarket unit-pricing pilot
↓
2026 → more supermarkets + more products
↓
2026 → online unit pricing begins
CASE says its Price Kaki app now covers more than 13,900 daily essentials, while this pilot is testing how unit pricing works directly at retailers. (CCCS)
So this is gradually moving Singapore toward a grocery-shopping environment where "How much does this actually cost per 100g/100ml/kg?" becomes visible at the point of purchase rather than something shoppers have to calculate themselves.
One important limitation
This remains a pilot, not a permanent mandatory nationwide requirement. Each participating operator is involved for eight weeks, and CCS says consumer feedback from the expanded phase will inform future decisions. (CCCS)
Bottom line: The reaction to the underlying idea is mostly positive, especially among price-conscious shoppers. The most useful consumer benefit is not that groceries become cheaper—it is that different pack sizes, "discounts" and potential shrinkflation become much easier to compare objectively. The big new test will be whether this works equally well online, particularly on RedMart.
