A discount store in Crosby is a type of department store, which sells products at prices lower than those asked by traditional retail outlets. Most discount department stores offer a wide assortment of goods; others specialize in such merchandise as jewelry, electronic equipment, or electrical appliances. Discount stores are not variety stores, which sell goods at a single price-point or multiples thereof. Discount stores differ from variety stores in that they sell many name-brand products, and because of the wide price range of the items offered. Many also operate as supercenters, which add a full-service grocery store to the traditional format.
