They may stock everyday groceries such as fruit and vegetables, bread, dairy products, meat, chilled and frozen foods, cupboard essentials and packaged snacks. Some specialise in a particular product or style of food, while others offer a wider selection for household shopping. Where fish is included, customers may find fresh whole fish and fillets, shellfish, chilled or frozen seafood, and prepared items such as smoked, cured or breaded fish. Staff may clean, scale, fillet or portion fish, and can often advise on suitable cooking methods and storage.

Food handling, storage and display are subject to food hygiene requirements, including appropriate temperature control for perishable goods.
