Abstract: A multi-merchant purchasing system is configured to identify downloadable products selected by a user for purchase. The identified downloadable products are offered by multiple merchants. The multi-merchant purchasing system enables the user to purchase all of the downloadable products in a single transaction. The multi-merchant purchasing system may also be configured to receive purchase information from the merchant applications and maintains the purchase information for the user in a locker. The multi-merchant purchasing system may further be configured to accept product license information from third party merchants not fully participating in the multi-merchant purchasing system. More specifically, a third party merchant may store product license information related to a user in the multi-merchant purchasing system such that the user may connect to the multi-merchant purchasing system at any time and manage all the user's product licenses in one central location.
