What should I do if the Shang Tong card is valid for three years?

Shopping cards have a time limit. Shopping malls last a long time, 2-3 years, and individual shopping malls last for 5 years. Generally, the gift card is 1 year. UnionPay shopping cards are also mostly for one year. However, after one year, most card issuers will not invalidate your card. This is the management fee. The management fee is deducted every month. Until the deduction is over.

If the supermarket shopping card expires, you can go to the customer service center to inquire. The system will find it soon. You can use it or apply for an extension.

Article 24 of the Law on the Protection of Consumers' Rights and Interests stipulates that operators shall not make unfair and unreasonable provisions to consumers by using standard contracts. If the standard contracts contain such contents, their contents are invalid. In this case, the relationship between supermarkets and consumers is actually a contractual relationship. After consumers pay the supermarket in advance and get the shopping card, they are the shoppers and consumers of the supermarket. In the course of operation, the supermarket should provide consumers with goods of the same value. The validity period marked by the supermarket on the shopping card is a unilateral statement, which is not binding on consumers. Consumers can still use shopping cards to shop in supermarkets.
