2,000 rounds for that price is pretty good. I've noticed that a lot of websites are out of stock. 7.62x39 must be going out of style!
Man, if the ammo industry isn't loving this war, the gunpowder manufacturers sure are!
I bought my 7.62x39 1000rnds at sportsmansguide.com - $89.97 (Came with a handy 7x11x6 steel ammo can). Try the link below - I'm not sure if this will work... but give it a SHOT. For some reason, if you use their search engine, it doesn't find the wolf ammo. Unless I don't know what I'm doing. I'm not sure which.

There's more sites, but I don't want to bore you. Without a doubt, the best deal I found was Sportsman's Guide. Plus, I think you get 10% off your first order or something like that when you create an account (and an ammo can!)
