I haven't been to one this year but I agree about the prices. The only reason I really go to one for is little stuff like cleaning jags, those boxes to put your rounds in, just junk in general. You have to be an educated consumer for everything now-a-days. I figure paying the entrance fee is like paying for shipping.
Two years ago I took a Marlin 695 slug gun to see what I could get for it and almost punched one of the vendors in the mouth for offering me $20. I got a piece of paper and wrote "For Sale" on it and sold it to a guy for $210 before I left the show.
