Method and system for processing supplementary product sales at a point-of-sale terminal

摘要

A point-of-sale terminal determines an upsell to offer in exchange for a round-up amount in connection with a purchase. In one embodiment, the point-of-sale terminal preferably maintains a database of at least one upsell price and a corresponding upsell to offer a customer in exchange for a round-up amount (e.g., change due the customer).
