If the store coupon is used when buying the baby, but the final transaction is unsuccessful or controversial, the coupon processing situation is as follows:

1. Before the delivery status, if the entire transaction order is cancelled or a full refund is successfully applied, the store coupon will be returned to the buyer, and the validity period will remain unchanged. If it is returned beyond the validity period, the coupon will be invalid;

2. If there is a transaction dispute after the goods have been delivered, the store coupon will not be processed according to the actual payment amount.
