I wouldn't walk away from 70's/80's Yugo @ $4.00 a box. Sure, it still shows up cheaper on rare occasion, but every time I buy some, I assume I may never see any ever again. AIM had it by the case about a year and a half ago, and it went real quick... luckily I got some from SGAmmo a few months ago, but that sold out in a matter of days as well.
