“Everybody loves a bargain.” Is a well-known saying. One person’s useless, ugly, or broken object can be another person’s bargain. That is why so many Americans do not throw things away.  They put them outside their house.  They put on a "For Sale" sign.  And, as simple as that, they have a yard sale.

The sellers put a paid announcement in a local newspaper.  It tells when and where the yard sale will take place. These sales are very popular during weekends in spring, summer, and autumn.

Early in the morning, all the things to be sold are carried out of the house. Then they sit all day in the sunlight -- like tired guests at a party -- waiting for someone to take them home.

Just about anything can be sold at a yard sale. Sometimes, there are more clothes than anything else. Cooking equipment is also popular. So are old toys, tools, books, tables, and chairs. Then there are objects called "white elephants."  A white elephant is something you think is extremely ugly or useless. It may be an electric light shaped like a fish. You feel a sharp pain whenever you look at it. To someone else, however, it might be a thing of beauty and joy.

Some people go to yard sales to find a special thing that they collect. It may be old toy trains, for example, or paintings of dogs. Experts say more Americans are collecting old things now than ever before. Most people who go to yard sales, however, are not looking for anything special.  They might buy an object simply because it costs so little.  They enjoy negotiating over prices, even if they really do not need the object.  Later, they may hold their own yard sale to sell all the things they have bought.
