Abstract: Products are selected for placement on check-out lane end caps at retail store locations. In one example, products are selected for placement on check-out lane end caps in one or more stores based on historical sales data for each product across all of the stores. Each check-out lane end cap includes a fixture configured to hold and display product(s) for sale in a store. A total number of stores into which each product is to be placed in at least one check-out lane end cap is received. A sales performance metric is determined for each selected product based on in-store historical sales data representative of sales of the product in each store. A particular store into which to place each selected product in a check-out lane end cap is determined based on the received total number of stores and the determined sales performance metric for the product.
