Patent attributes
An electronic marketplace, or other website, may be configured to support customer returns using a “return cart,” allowing a user to combine items, purchased in different transactions, in a single return. In some cases, the user may be able to browse a purchase history including several different orders, and select items from different orders to add to the return cart. The electronic marketplace may process the combined returns as a single transaction and provide an identifier that is common to all the items in the combined return, such as a return number, a shipping number/label, etc. In some examples, the return cart may be persistent and/or associated with a user account, thereby allowing it to be accessible at different times and/or from different devices. A return cart may also be combined with a “shopping cart,” which allows the customer to purchase, exchange and/or return items in a single transaction.
