International Market World is a very large flea market just west of Auburndale, Florida. This flea market is on the north side of U.S. Highway 92. Just to its southwest is the intersection of US 92 and Polk Parkway (State Road 570). International Market World is open every Friday, Saturday and Sunday throughout the year. Its website posts hours of 8 AM to 4 PM. However, it is evident most vendor stalls are closed by 3:30 PM.
