A flea market is a place where vendors come to sell their goods. The goods are usually cheap. Flea market shopping is a popular pastime for many people in the Western world. The vast majority of goods sold at flea markets are second-hand, but their semi-spontaneous nature and vendor-oriented open-market layouts differentiate them from thrift stores.
Many television shows (starting in the late 1990s) focus on the appraisal of second-hand goods, often found at flea markets, that turn out to be worth far more than the buyer paid for them. In the United States, the most popular of these television shows is Antiques Roadshow.
