A few days ago, I went to Amazon to see things, and I accidentally clicked on a button to place an order. How to cancel it now?

Follow these steps: My Account → Payment Settings → Manage your payment method → If you want to edit the payment method of the order, click here and cancel deleting the list. The so-called text before the code is also to facilitate you to delete one-click orders. I've been using it and it feels good.
