In an Alipay guaranteed transaction, when the transaction status is "waiting for buyer's payment", the seller can modify the price of the order.

You can go to "My Alibaba" to find and enter the "Seller Transaction Management" application, click the "Sold Goods" menu, find the order with a transaction status of "waiting for buyer's payment", click "Modify Price", and you can adjust the shipping cost and price increase or discount (negative number represents discount). After confirming that the actual payment calculated is correct, click "Confirm". Warm reminder: After modifying the price, the current transaction status remains unchanged, and the seller can modify the price again or close the transaction.
