A supermarket is a large self-service store selling a wide range of groceries and household goods at low margins and high volume. Its features: self-service, wide range under one roof, low prices, high stock turnover, fixed prices, centralised checkout, cash and carry, bulk buying, attractive display, chain ownership and convenient location.
In 1930, Michael Cullen opened King Kullen in Queens, New York, and is usually credited with creating the modern supermarket: a large self-service store selling groceries at low margins and high volume. Ninety years later, India’s most profitable grocery retailer, DMart, runs on almost the same formula: everyday low prices, a tight range of fast-moving goods and stores it owns rather than rents.
Here are the features that define a supermarket and the benefits they bring to shoppers. For the downsides, read the advantages and disadvantages of supermarkets.
Features of a Supermarket
1. Self-Service
Customers pick goods off open shelves themselves, which cuts staff costs and lets people browse.
2. Large Range Under One Roof
Groceries, packaged food, fresh produce, household goods, personal care and often clothing and kitchenware.
3. Low Prices, Thin Margins
Supermarkets earn a small margin on each item and make money through volume. DMart aims to sell below the MRP on most items every day rather than run occasional sales.
4. High Stock Turnover
Fast-moving goods sell out quickly, so cash is not tied up in slow stock.
5. Fixed, Marked Prices
No bargaining. Every item carries a price label or shelf tag.
6. Centralised Checkout
All purchases are paid for at billing counters near the exit, usually with cash, cards or UPI.
7. Cash and Carry
Most supermarkets do not offer credit or home delivery as standard, though many now add delivery through apps.
8. Bulk Buying From Manufacturers
Large orders direct from companies earn better terms than small shops can get.
9. Attractive Display and Packaging
Layout, end-of-aisle displays and packaging do much of the selling that a shopkeeper does in a kirana store.
10. Owned by Large Companies
Most are run as chains by companies such as Avenue Supermarts (DMart), Reliance Retail (Smart Bazaar) and Spencer’s.
11. Convenient Location and Parking
Stores sit in residential areas or on main roads with space for vehicles.
