In commerce, a hypermarket or multi-department store is a superstore which combines a supermarket and a department store. The result is a very large retail facility which carries an enormous range of products under one roof, including full lines of groceries and general merchandise. When they are planned, constructed, and executed correctly, a consumer can ideally satisfy all of his or her routine weekly shopping needs in one trip.
