This study was primarily designed as a pilot to ascertain the feasibility of collecting and reducing data into manageable form for evaluation purposes. Twenty-one months of weekly sales data from two grocery stores were acquired through a marketing research firm. Grocery sales data appear to be useful in evaluating the impact of community-wide nutrition intervention programs. It is extremely resource intensive to use computerized sales data for evaluation purposes; however, advances in technology are making this process less burdensome. The complexities of assigning universal product coded (UPC) foods to specified study categories require careful attention. Use of outside resources is recommended. These include an intermediate processing center and a computerized database of UPC foods and their nutritional values.
