Non-specialised food businesses sell a broad range of everyday food and grocery products rather than concentrating on one particular type of food. They may operate as grocery shops, convenience stores or larger food retailers, offering a mix of ambient, chilled and frozen goods. The range commonly includes bread, dairy products, meat, fruit and vegetables, tinned and packaged foods, snacks, soft drinks and basic household groceries. Customers may also find prepared foods, bakery items, ingredients for home cooking and products to meet common dietary requirements, depending on the business. Some retailers provide services such as home delivery, collection of online orders or the preparation of simple foods, but these are not features of every business in the category. Stock, opening arrangements and the balance between fresh and packaged goods vary according to the size and format of the retailer.
