Check over at the ar15.com equipment exchange -- lots of really good deals on mags there right now. You can get D&H 30rnd mags for 10/mag shipped if you buy 10 at a time. That's a good deal on good mags.
You asked too late. Bravo Company was blowing out magazines for 8.99 each to combat 44mag.com's prices. I received an email from them about 2 weeks ago saying they're completely out and they're not running the promotion any further.
That would've been a steal. $9 mag + $2 follower and you get top notch magazines for $11 each.
