#24 hour supermarket singapore

Eight supermarket chains, re-checked against their own official pages on 13 October 2026. In October CHAS cardholders get 6% at all three big chains, on Thursdays for Blue and Fridays for Orange: Sheng Siong and FairPrice to 1 January 2027, and Giant from 1 to 30 October after its every-day September round ended on 25 September. Sheng Siong is still the cheapest place to buy staples, and its 4% senior discount runs Tuesdays and Wednesdays only, not daily. Giant's weekend card deals ($5 off $50, $8 off $80) run to 25 October, Cold Storage's $7 off $80 ended on 18 October, and Sheng Siong now has its own: $8 off $80 every weekend with the BOC Sheng Siong Card to 31 January 2027. Plus Scarlett for China-imported snacks, Mustafa for 24/7 bulk, Don Don Donki for Japanese, and the CDC voucher rule that trips everyone up.

Sheng Siong has opened a brand-new 24-hour outlet at Blk 361 Sembawang Crescent, #01-10 (S750361), and is marking it with a 7 Days Special — up to 62% off plus free gifts — running 3 to 9 July 2026. The gift-with-purchase is the headline: spend $70 in a single receipt for an exclusive gift bundle, or spend $30 for your choice of two dishwashing-liquid options (one redemption per receipt, while stocks last; cigarettes, liquor, Sheng Siong vouchers and infant milk powder stages 1–2 excluded). Expect deep cuts on housebrand items, groceries, beverages, household goods and fresh produce, with a max of three units per customer per item. Handy extras at this outlet: 4% senior-citizen discount on Tuesdays & Wednesdays and CHAS-card discounts on Thursdays & Fridays, both till 31 Dec 2026. Bonus for north-side residents — it's open 24 hours.
