Abstract: Systems and methods including techniques for allowing users of an electronic marketplace to create “Giveaways” on the electronic marketplace are described. For example, a user (“host”) can purchase a certain number of items using the electronic marketplace, and set parameters for others to redeem or claim those items. The electronic marketplace charges the host for the items and other estimated costs, reserves the requested number of items, and sets up a redemption site through which other individuals can claim the items according to the parameter(s) set by the host. The electronic marketplace may validate winners of the giveaways by confirming user identities, addresses, etc., using their own user database. When items are claimed, actual costs, such as shipping, taxes, etc., may be calculated, and the electronic marketplace can send a refund to the host for any overcharges, as well as any unclaimed items.
