Every weekend, many Americans drive around looking for things to buy. They are taking part in an unusual kind of outdoor treasure hunt: the yard sale (旧货出售). In some parts of the country, such a sale might be called a garage sale or a moving sale. Whatever the name, the activity is the same. People sell things they no longer want.

The sellers put a paid announcement in a local newspaper. It tells when and where the yard sale will take place. It lists some of the things to be sold. Early in the morning, all the things to be sold are carried out of the house. Then they sit all day waiting for someone to take them home. Usually, the seller puts a price on each object at a yard sale. However, that price can almost always be negotiated (谈判).

Serious buyers also spend time getting ready for yard sales. They collect the newspaper announcements. Then they make lists of the sales they want to attend.

Most people who go to yard sales are not looking for anything special. They might buy an object simply because it costs so little. They enjoy bargaining over prices, even if they may hold their own yard sale to sell all the things they have bought.

To other people, yard sales are simply a way to have fun. In some communities, they are important social gatherings. Other people say yard sales help the environment. Old things are re-used instead of being thrown away.

In any case, yard sales are very popular in America. Hunting for unusual items is a sport for some people. For others, it is a way of life.
