Supermarkets usually offer products at low prices by reducing margins. To maintain a profit supermarkets attempt to make up for the low margins with a high volume of sales. Customers usually shop be putting their products into trolleys ( shopping carts) or baskets (self-service) and pay for the products at the check-out. At present, many supermarket chains are trying to reduce labor costs (and thus margins) further by shifting to self-service check-out machines, where a group of four or five machines is supervised by a single clerk.

Early retailers did not trust their customers. In many stores, all products had to be fetched by a clerk from high shelves on one side of a counter while the customer stood on the other side and pointed to what they wanted. This was obviously labor-intensive and quite expensive.
The concept of a self-service grocery store was developed by Clarence SaundersClarence Saunders (August 9, 1881 October 14, 1953) was a grocer who first developed the modern retail sales model of self-service. His ideas have had a massive influence on the development of the modern supermarket.

Piggly Wiggly was the first true self-service grocery store.

The general trend in retail since then has been to stock shelves at night and let the customer get their own goods and bring them to the front of the store to pay for them. Although there is a higher risk of shoplifting, the costs of appropriate security measures will be ideally outweighed by the economies of scale and reduced labor costs.
The first true supermarket was opened by ex- Kroger employee Michael J. Cullen, in 1930 in a 6,000 square foot (560 m²) former garage in Jamaica, Queens, New York. The store, titled King Kullen , following King Kong, operated under the slogan "Pile it high. Sell it low." When Cullen died in 1936, there were fifteen stores in operation.
Supermarkets proliferated along with suburban areas after World War II. Supermarkets in the USA are now often co-located with department stores in strip malls and are generally regional rather than national. Kroger is probably the closest thing in the U.S. to a national chain but has preserved most of its regional brands like Ralphs.
It was formerly common for supermarkets to give trading stamps.
In Britain, Denmark and other European countries the proliferation of out-of-town supermarkets has been blamed for the disappearance of smaller, local grocery stores and for increased dependency on the motor car.
