Hong Kong consumer watchdog questions supermarkets’ buy-one-get-one-free deals

Hong Kong shoppers may have saved less than they expected – or nothing at all – through supermarkets’ “buy-one-get-one-free” and bulk-buy promotions, the city’s consumer watchdog has warned, urging residents to compare unit prices instead of relying on promotional labels.The Consumer Council on Monday released the findings of a survey of 222 products sold by AEON, ParknShop and Wellcome between September 2025 and July this year. It found that the actual discounts offered in some promotional campaigns were less attractive than consumers might expect.During the period, 48 products at two supermarkets were offered under bulk-buy promotional campaigns, such as ‘Buy 1 Get 1 Free’, ‘Choose Any 2 and Get 1 Free’ and ‘Get 1 More for $1’.
