A garage sale is an informal event for the sale of used goods by private individuals, in which sellers are not required to obtain business licenses or collect sales tax.

Used goods, also known as secondhand goods, are any item of personal property offered for sale not as new, including metals in any form except coins that are legal tender, but excluding books, magazines, and postage stamps. Used goods may also be handed down, especially among family or close friends, as a hand-me-down.
