     Shopping in the United States changes a lot. About ninety years ago most people shopped in small stores

that were owned by one person or a family. Women went from the bakery to the butcher's to the grocer and

on to the fruit and vegetable seller in order to get their food for the week.

     Then about sixty years ago, supermarkets were born. In a supermarket, people could get all the different

kinds of food they needed without going to different stores.

     The next big change in shopping in the United States was the shopping mall. A shopping mall is a group of

stores under one roof. Because malls allowed people to shop without worrying about the weather, they soon

became very popular. The mall became a place for people to socialize in addition to shopping. If you walk

through a mall, you will see older people sitting, chatting and drinking coffee. Malls are places for teenagers to

hang out. Many teens will often just "go to the mall" and spend time with their friends.

     The recent change in American shopping was the superstore. Large chain stores such as Wal-Mart, Office

Depot and Toys "R" Us have been built all across the United States. Because they are so large, they can buy

goods at a great discount and sell them much cheaper than smaller stores.

     Sometimes, when they are built near small towns, many of the small town stores have to close. They just

cannot compete with their giant neighbors.

     And now, online shopping is becoming more and more popular all over the States. People are too busy to

go to the physical stores, so they go shopping over the Internet. Online shopping has lots of advantages. For

instance, online stores are usually available 24 hours a day. Searching or browsing online shops can be faster

than browsing the physical stores. While, online shopping also has its disadvantages. People are at higher risk

of being cheated on the part of the merchant than in a physical store. And privacy of personal information

may be let out.
