Sales of different products at respective sale times are recorded on a sales terminal at the point of sale. A relationship between the sales times of at least one of the products and the display times of at least one of the promotional images is measured. Responsively to the relationship, a change is made in the sequence of the promotional images that are displayed on the display terminal.
