Yard sales do not have to be huge. One family, or even one person, can hold a yard sale. People simply collect some things they no longer want and put them in the yard outside their home. They might also place handmade signs on nearby streets to direct people to the sale. Yard sales are a good way for people without much money to find things for their family. But even people with a lot of money like to look around. Professional dealers might also go to yard sales. If they find something valuable at a low price, they can re-sell it for more. Still other people go to yard sales because they enjoy the hunt. They like to find beautiful or unusual things that are being sold for less than the value. For example, they may find a piece of old furniture that is worth a lot of money after it is repaired.
