A supermarket is a self-service shop offering a wide variety of food, beverages and household products, organized into sections. It is larger and has a wider selection than earlier grocery stores, but is smaller and more limited in the range of merchandise than a hypermarket or big-box market .

A supermarket is a large retailing shop where goods are displayed in such a way that buyers select products for themselves. Buyers collect their product off the shelves invariably in a trolley and get them billed by the counter clerk.
