1. The balance in the supermarket card can be returned by contacting BBK supermarket customer service with the supermarket card and ID card.
2. If the supermarket card has an expiration date, you can contact the customer service staff to extend the expiration date of the supermarket card so that it can be used in other cities.
3. If BBK supermarket has nothing to buy, you can choose BBK to refund, but you need to abide by the corresponding deposit policy and shopping card management measures.
