A grocery store (AE), grocery shop or grocer's shop (BE) or simply grocery is a retail store that primarily retails a general range of food products, which may be fresh or packaged. In everyday US usage, however, "grocery store" is a synonym for supermarket, and is not used to refer to other types of stores that sell groceries. In the UK, shops that sell food are distinguished as grocers or grocery shops (though in everyday use, people usually use either the term "supermarket" or a "corner shop".) Larger types of stores that sell groceries, such as supermarkets and hypermarkets, usually stock significant amounts of non-food products, such as clothing and household items.
