A flea market is a type of open-air market where vendors sell secondhand or used goods, antiques, collectibles, and handmade items. The term "flea" comes from the French word "marché aux puces," which literally means "market of fleas," and was used to describe the used clothing and furniture that was often infested with fleas.

Flea markets can be found in many cities and towns around the world, and they are popular among bargain hunters, collectors, and people looking for unique and one-of-a-kind items. They offer a great opportunity for vendors to sell their goods directly to the public, without the overhead costs associated with a brick-and-mortar store.

Flea markets can be a fun and exciting way to spend a day, as you never know what you might find. Some of the items commonly sold at flea markets include vintage clothing and accessories, vinyl records, antique furniture, books, toys, artwork, jewelry, and handmade crafts.

In addition to shopping, flea markets are also a great place to socialize and meet new people. Many flea markets offer food and refreshments, as well as live music and entertainment. Overall, flea markets are a great way to support local businesses and find unique items that you may not be able to find anywhere else.
