Excerpts from the report Summary: Fewer rows of display per item and more items stocked would likely increase the gross profit of retail food stores. This was the conclusion drawn from an experiment in 5 supermarkets located in an eastern metropolitan area. The experiment included 17 representative canned fruits and vegetables. Effective utilization of the selling space in retail food stores helps reduce the cost of retailing. Lower retail costs are of immediate help to the retailer and, in the long run, reductions in marketing costs help producers and consumers.
