A supermarket is a large, low-cost, low-margin, high-volume, self-service retail outlet that offers a wide variety of food and household goods. It is the most common type of grocery store.
Supermarkets rely on high volume sales and self-service to achieve high profitability. They are constantly competing with discounters (such as Lidl, Kaufland) and larger superstores (such as Carrefour) by adding services and emphasizing the in-store experience.
