Abstract: Methods and systems for exchanging stored value for shopping at a vendor using a mobile device involve identifying, by an application on the mobile device, a vendor for a user's shopping. Information regarding a trade of stored value of the user issued by at least one other vendor in exchange for stored value issued by the vendor for shopping by the user is retrieved by the application, and at least a portion of the stored value of the user issued by the at least one other vendor is identified by the application to exchange for stored value issued by the vendor for shopping by the user. Thereafter, the stored value issued by the vendor for shopping by the user is received by the application in exchange for at least a portion of the stored value of the user issued by the at least one other vendor.
