An operator-unattended system for the processing of articles selected for purchase includes a subsystem for processing coupons bearing codes indicative of the identity of an article and a coupon monetary value. The subsystem comprises a coupon receiver for reading the codes of received coupons and generating first and second output signals per coupon read and respectively indicative of the article identity and the monetary value, the coupon receiver being responsive to a control signal for returning the coupon to a customer of the articles. A storage device stores signals indicative of the identity of all articles selected for purchase by the customer as derived from the operator-unattended system. A coupon validator compares the first signals obtained from the coupon receiving means with the stored article identity signals and generates a coupon validation signal for each positive comparison, the coupon validator further generating the control signal upon each negative comparison and applying the same to the coupon receiver. A coupon discount totalizer receives those of the second signals of the coupon receiver for which a coupon validation is generated and a signal, derived from the operator-unattended system and indicative of price totalization for all the articles selected for purchase and substracts the monetary value in each the received second signal from the monetary value indicated in the price totalization signal.
