If you have an Academy near you, I have found them to have the best prices of CCI Blazer aluminum. I have put about 10000 rounds through my Glock 19 without any problems. I also buy the Wally World CCI Blazer Brass from time to time, but the aluminum stuff from Academy is only $6.99 per 50 round box here, or it was the last time a bought some a few months ago. Oops, just checked online, and it is now $7.99 per box. I recently bought CCI Blazer Brass from Wal Mart for $7.89 per box. Sounds like about $8.00 per box is about as good as you are going to do. I am going to stock up this evening.
