hypermarkets have extensive parking lots. They are usually located in the outskirts of towns, and in the vicinity of motorways and elevated roads. They have long opening hours and offer a wide range of products, especially foodstuffs, but also cleaning, personal hygiene and household products, and clothing. They usually combine a supermarket with shops and department stores in the neighbourhood. Hypermarkets can offer low prices thanks to their large sales volume, frequent product rotation and a reduced customer service staff.
