Yonghui Supermarket shopping cards are not available all over the country, but there are regional restrictions. For example, cards in Southwest China can be used in Chongqing, Sichuan and Guizhou. The whole country is divided into East China, Central China, South China, Southwest China, Northwest China, North China and Northeast China.
Using a shopping card is more economical than paying cash or swiping a card, especially when buying large items such as gold jewelry, electrical appliances, cosmetics, clothing, shoes and hats. It is especially suitable for large-scale procurement activities such as online shopping and group buying.
