An in-store experiment was performed to investigate the effects of a point–of–purchase display on unit sales of Shopping bag. The experimental conditions consisted of periodically placing two copies of the same display in convenience stores and supermarkets. The results were, point-of-purchase displays did change relative sales of the target brand. An antecedent intervention such as a point-of-purchase informational display is quite sufficient to change consumer choice in the presence of utilitarian reinforcement in the form of a lower-priced competing product.

So this requires a movable display that have wheels. We solve this problem by adding a strong piece of MDF board on the bottom of the Point Of Purchase Cardboard Display Stand with Rotary Wheels, and add 4 wheels that can support all the goods above.
