Singapore's competition and consumer agency (CCS) said on 28 September that NTUC FairPrice, Sheng Siong, Prime Supermarket, Don Don Donki and RedMart join the unit pricing scheme from 1 October 2026, with Cold Storage and Giant following on 1 November. More items are covered, including flour, milk, butter, snacks, soups and sauces. Unit price means the price for the same amount, such as "$X per litre" or "$Y per kg", so a bigger pack is not always the better deal — check the unit price before you buy.
