The majority of locals shop in supermarkets, because they offer all sorts of products at very reasonable price. Sometime a product can be 20 percent cheaper in a supermarket than in convenient stores.
These supermarkets are run by Chinese retailers as well as foreign companies.
Big supermarkets include Lotus, Carrefour and Lianhua, some of which are offering imported goods.
Before entering the supermarket, don't forget to put your carrying-on into a locker outside the supermarket and keep a paper with password.
Remember to watch out the expiry data for fresh foods, such as yogurt.
