The last one I went to was hawking those bamboo pillows.My experience has been exactly the same. The only items I have found that I was remotely interested in were used firearms, but invariably priced way out of my range. All new firearms were priced at least $100 over prices easily found on the internet. Newly manufactured ammunition was also grossly overpriced.
Most tables have nothing but junk knifes, belt buckles, a bunch of completely unmarked and worn out pistol magazines, reloaded ammo, and other stuff I have absolutely no interest in. I have stopped attending.
