Just for Feet, Meldisco (the licensed footwear division of Kmart), Pamida, and Payless Shoe Source are among the latest retailers to sign up to The NPD Group Inc's point-of-sale tracking panel. Each new retailer will provide NPD with detailed information on product movement throughout its stores. This information will in turn be used by marketing information provider NPD to enhance point-of-sale tracking reports for a range of industries. Subscribers use NPD point-of-sale tracking services to monitor sales volume, share and trends by category, brand, item and price point.
