...and then click the "specials" tab on the top row for free shipping if you buy $100 worth of Tula primers. Good prices and good folks to do business with.
Natchez Shooters Supply typically has the best online price for rifle powder and primers that I've seen (I use RL-15 and BR-2's exclusively) and they have most beat, and the shipping time is ridiculous fast! Placed an order Friday for some mags cause they were on sale, I had them Tuesday even with the holiday.
You will be hard pressed to beat Aszerigan's deal once you add in the hazmat fees. I haven't had to buy powder/primers in a while, but when I do I will be looking him up.
