Hi-Fi Fo-Fum was an American audio equipment store of the 20th and 21st centuries. It was located in Richmond Heights, an inner suburb of St. Louis, Missouri, and was in operation from about 1960 until 2011. The name was a variation on fee-fi-fo-fum, with the phrase "hi-fi" interpolated. Hi-fi Fo-Fum was given the award for Best Electronics (retailer) in 2010 by the St. Louis Riverfront Times. Attempts by former manager Tony Dollar to keep the store intact after Biffert's death were unsuccessful, and the enterprise was liquidated by Biffert's daughter.
