Method and system for using a point-of sale system to correlate transactions to a coupon database

A system and method for providing relevant coupons at the point of sale includes a process for providing relevant coupons at the point of sale whereby a coupon database is provided with at least a portion of the coupon database, and the coupon data in that portion, being associated with a given user. Electronic data representing one or more coupons, and/or other marketing devices, associated with, and/or offered to, the given user is then provided to the coupon database and stored in the portion of the database associated with the user. A computing system implemented point-of-sale system is then given access to the coupon database and/or the portion of the database associated with the user at the time of a transaction being made through the computing system implemented point-of-sale system. Data and/or search parameters from the computing system implemented point-of-sale system are then used to search the portion of the database associated with the user to find any relevant coupons applicable to the user's current transaction. Any relevant coupons are then provided to the user and/or are automatically applied to the current transaction.
