people who type buy are morons lol.
if you buy 10 lots of shotgun and get 150 ammo, then buy one lot of sawns and get 12 from them, your shotgun bullets change into sawns so you get 162 sawns for the price of 150 sg and 12 sawns.
that's how I buy 35? k of bullets[without m4's etc] and buy exactly the same as lisa
