There is ammo to be had. If all you have or go to is WM, then you're S.O.L. right now.
I just bought 1000rds. 9mm & 2000 rds. .22lr at reasonavle prices, within the last 2 1/2 wks. Don't be lazy, call ahead if you have to, but let's cut out all of the histrionics & conspiracy theory crap. Ammo is tight but it is the LAW of supply and demand that is at work here.
ie.: I deal in fresh, local produce in the summer. Every 4th of July & Labor Day the price of sweet corn & tomatoes triples and supply is always tight. There is no conspiracy to "jack-up" the price by limiting supply, it's just that demand is at it's annual high.
You'll get your ammo, but right now your going to pay a premium & just like July 4th & Labor Day some people get shut out!
And as per the O.P., yes people take advantage of this type of situation!
