Not a pmag, but PSA has their aluminum 30rd mags with magpul followers for $8 each shipped to your door if you buy 20 or more. A year from now, people will regret not buying these. D&H 5.56 30rd Aluminum Magazine
Killer deal at PSA right now. 12 Pmags, a magpul rear flip sight, and aimpoint ACO for $399. Sell the aimpoint for $300 and the rear sight for $35 and you have 12 Pmags for $65. I'm debating picking this up.
