When the supermarket closes down, it is necessary to pay the purchase price in order. If the business really goes out of business, it should refund the unused amount in the citizen's shopping card. If consumers do not get a refund, they can register at the industrial and commercial office in their jurisdiction. According to the relevant laws and regulations, if the accumulated amount of money owed by merchants to consumers in shopping cards is relatively large, if it exceeds 50,000 yuan, the industrial and commercial department will hand it over to the public security department for legal treatment.
