To view past orders from your Amazon.com account, hover over Your Account and click Your Orders. From there, you can view all orders placed with your account. You can change the year the order was placed from the drop-down list.
From the Your Orders screen, you can return or replace a purchased item, track a package or leave feedback for past transactions. For older purchased items, there is an option to write product reviews. Third party sellers on Amazon.com may have their own return policies, but you can only return orders purchased directly from Amazon.com and its Warehouse Deals for 30 days.
