To make a purchase using Amazon Pay, customers need to log in with their Amazon account. They can do this from two places:
Cart sign in widget
On the cart page, there is an Amazon Pay button next to the regular checkout button:
Checkout sign in widget
On the regular checkout page, there is a banner asking customers if they want to use Amazon Pay:
When either button is clicked, it triggers a sign-in window to appear. The sign-in window looks like the screenshot below:

Customers choose their desired shipping address and payment method, and this refreshes the Great American Computer order totals as normal. At that point, the customers can click the place order button. This creates an order in the Great American Computer system for you to process.
