Nah, I think we're seeing the horders have bought as much as they're going to buy, and the regular folk who aren't going to spend $0.40 per round for 9mm WWB just aren't buying at those prices. The ammo vendors will see the trend and lower prices accordingly. You are seeing basic economics at work right now. If the vendors were lucky to break even, that is their own fault for not seeing the market trends and adjusting prices accordingly.
As for me, I don't see myself visiting a gun show anytime too soon, even though Crossroads of the West occurs less than 5 miles from where I live.
