So ya boy said fuck it and went to a moderate size show near me on a Saturday at opening. Was walking around and 1 guy had stuff physically on the ground below his table he had PPU (serbian) m193 1k rds for $375. I offered 350 which he took. Later that morning I found a guy who had an ammo can of 500rds federal 5.56 (like the ones you'd see at cabelas) and he was asking around $225 (45cpr) and I was getting ready to walk and he asked what id take it for. I said $175 (35cpr) and he took it. Honestly dude I think what I encountered there was desperate people who bought shit they didnt need and needed cash more than the ammo. People were very open to negotiating so it might be worth your time if you have some good shows near you
