US Patent 7236942 Pre-sale data broadcast system and method

A method for promoting the sale of a substitute product at the point of sale (POS). At least one POS terminal communicates with a POS server which in turn communicates with various manufacturer servers to transmit information therebetween. Upon the presentation of an original product for purchase by a consumer at a POS terminal, various manufacturers may decide to offer a substitute product to the consumer, prior to completing the purchase of the original product. As such, various manufacturers may offer promotional offers to encourage the buyer to favorably “switch” products. If the customer accepts the offer, the point of sale terminal completes the sale of the substitute product.
