A car boot sale is a type of open-air market where vendors sell used goods directly from the trunk, or "boot," of their cars. However, this term may vary depending on where you are from. In the US, it is often referred to as a flea market or a garage sale. In Australia, they call it a "garage sale" or "yard sale." In South Africa, it is known as a "boot sale," "car boot market" or "trunk sale." In Canada, it is referred to as a "swap meet." No matter what you call it, these types of sales are a great way to find unique items at bargain prices.
