Abstract
A coupon dispensing system which displays a number of images, each image representing a product to be promoted and including a product selection area to be manipulated by a consumer to select that product. A switch is associated with each selection area to register the selection. The system receives an access code unique to the consumer, records product selections made by the consumer, compares the product selected by the consumer with a preselected quota, and issues a coupon for the product selected by the consumer if the quota for that consumer is not exceeded.
