Amazon will not automatically deduct the money from another credit card if the order is not paid successfully. Amazon's deduction failed, you can leave it alone! Amazon is an international shopping platform, where you can choose what you like, add it to the shopping cart or buy it directly, but after placing an order, it doesn't matter if there is no payment, because the order will be cancelled automatically if it is overdue!

it won't deduct money, and it won't deliver goods to you. It will let the next buyer buy it, which will have no influence on you and the seller.

How to deal with the buyer's unpaid order before it is closed by the system?

If you don't want it after placing an order but pay by credit card before delivery, you can temporarily lock the card first. Amazon generates the pre-sale right when the goods are delivered, and its own logistics shows that the goods will be deducted. However, if you close the credit card limit before it has the pre-sale right, the order will fail to be deducted. You just wait for him to prompt that the deduction failed.
