You got their email flyer today, too, eh?
I just picked up 10 AR mags on sale at 44mag.com. They were only $9.49 each, made by D&H. Sale is still on.
Oh, and If you buy over $100, shipping is free, so I bought 10, plus a ten-rounder for use when I go to NY to shoot. Basically got a magazine for free, once you factored in the free shipping.
