A supermarket is a large retail store that sells a wide variety of food and household items. Customers can find fresh produce, meats, dairy products, canned goods, and cleaning supplies all in one place. Supermarkets are designed for self-service, allowing shoppers to browse aisles and select items they need. Most supermarkets also offer additional services, such as a bakery, deli, and pharmacy. They often have weekly sales and promotions to attract customers. Supermarkets are an essential part of modern shopping, providing convenience and a diverse selection of products for everyday needs.
