Abstract: An expanded display unit for communication with a customer in a supermarket checkout facility is furnished with information from a system responsive to UPC signals provided by a scanner. Such system discerns selected characteristics of the customer, particularly deducing from products selected for purchase, other products which may be of interest to the customer. The system then provides information respecting the other products to the display unit, which may be customer-interactive for the dispensing of coupons or the like.

Abstract: An expanded display unit for communication with a customer in a supermarket checkout facility is furnished with information from a system responsive to UPC signals provided by a scanner. Such system discerns selected products selected for purchase from such UPC signals, such products being those in connection with which a promotional plan has been preestablished, either for such products or other products. The system then provides information implementing the promotional plan to the display unit, which may be customer-interactive for the dispensing of coupons or the like.
