n the US a shopping center is a place where many different shops and stores are collected under one roof. You can buy everything you want there.
There are other places which are called five-and-ten-cent stores because they used to sell things for five or ten cents. Today they sell almost anything and some of the things cost several dollars. Supermarkets are found in all the cities. They sell food and many other goods. You walk around the supermarket, choose the things you want, put them in a special basket prepared by the store and pay for them all together at the door. Supermarkets often stay open and are closed later than the other places. Stores are always open every day of the week except on Sunday. Some are also open on Sunday in July And August.
