First, you need to go to the supermarket in Zhong Bai in your city. Choose the goods you need to buy in the supermarket.
Next, when checking out, give the gift card to the cashier and tell you to pay the current shopping bill with the gift card.
The cashier will use the gift card of Zhong Bai Supermarket to pay the bill. The system will verify the validity and balance of the gift card. If there is enough balance on the gift card, the system will deduct the corresponding amount and complete the transaction.
Please note that if the balance on the gift card is not enough to pay the whole bill, you may need to use other payment methods to make up the difference. Some supermarkets in Zhong Bai also offer cash and credit card payment options.
After paying with the gift card, the cashier will print out the shopping record and the balance on the gift card will be updated. You can check the balance on the shopping card at any time and keep the shopping card as the payment method for future shopping.
