This paper reports the design and baseline results of a rewards-based incentive program–the Frequent Buyer Rewards Study–in a large full-service supermarket located in a predominately minority community in Philadelphia, Penn.

Households purchased an average of 3.7 servings of fresh vegetables; less than 1 serving of frozen vegetables; 1.9 servings of fresh fruits; and little to no frozen fruit purchases per week.
