What is the best way to look up my past orders on Amazon.com?

To look up your past orders on Amazon.com, log in to your account on the home page, and click on Your Orders. This displays all past orders made from your Amazon.com account.

You can select between past orders, currently open orders and cancelled orders. In the Past orders, you can choose between orders placed in the last 30 days, past 6 months and past years in which orders were placed. Once you've selected your time frame, Amazon.com displays the orders you have placed, the price paid, tracking information for the item, and how to cancel the order or buy it again.
