A method for customer promotion includes sequentially receiving signals indicative of respective bar codes of a plurality of items in a customer order. The price of each item is accumulated. A marginal discount associated with each item processed is generated. This marginal discount is generated in response to a signal that indicates the accumulated price exceeds a predetermined threshold. Unapplied marginal discounts are accumulated for application to the customer order. A discount is applied to the customer order in response to a signal that is generated that indicates the accumulated discounts exceeds a predetermined minimum.
