Sheng Siong has flipped over to a new CDC Voucher week, running 21 to 27 July 2026, and this round is one of the better ones: 12 featured products at cut prices, with the biggest markdowns on the cupboard-and-cleaning staples rather than the token loss leaders. Happy Family Premium Oyster Sauce 550g drops to $1.25 from $3.95 (68% off), Homeniks 6-in-1 Laundry Capsules 80s to $8.95 from $26.90 (66% off), and a 6-pack of F&N Sparkling Zero to $1.95 from $5.60 (65% off). Heritage Farm Classic Basmati Rice 5kg is $9.65 down from $18.50, Dynamo Laundry Detergent 2.5kg is $8.65 from $18.90, and Happy Family Canola Oil 3L is $8.95 from $13.90. Sheng Siong's own poster puts total savings at up to $70.18, an average 43% off. The mechanic is the part people get wrong: for every $20 worth of CDC Supermarket Vouchers you spend in a single transaction, you unlock one unit of each featured product at the special price — so it is the voucher spend, not your cash spend, that opens the prices, and it is one unit each, not unlimited. Ends Monday 27 July, while stocks last.
