I've found that pawn shops are usually the best way to get rid of stuff you don't want. They'll usually cut you a decent deal. The best part is that there aren't any questions asked. They'll just take the stuff and resell it later. It's very liberating.
Best Pawn Shop St. Louis 2009 - Bel-Air Pawn Shop, Inc.
Bel-Air Pawn Shop, located deep in the belly of south St. Louis, has everything a great pawn shop needs. It's big, and it houses an eclectic inventory — everything from the obligatory musical instrument and stereo equipment section to bicycles and televisions and a sizable selection of lawn mowers, leaf blowers and power tools. The sprawling, windowless warehouse of wants is a veritable boulevard of broken dreams — a place where someone else's hard luck or throwaway merchandise from another life practically begs to be snatched up as your treasure. Just don't expect to haggle.
Throughout history, people from all walks of life have used pawn shops from Kings and the rich to your average Joe. You can buy and sell things at a pawn shop and use your valuables as collateral for a loan.

What about D&R Pawn and Jewelry in Maplewood? Lots of guitars and electronics, located next to Eddies Guitars and the Pro Sound Store, worth the trip to see all of them! Great jewelry selection and the pet birds are cool!
Maybe next year!
