Another thing that may seem obvious , but than can save you a good deal of money, is efficent grinding. I recently tightened my mill a hair and am getting about 15% more for the same amount of grist. Of course you don't want to go too fine, but it is easy to get camplacent about your mill settings. Size varies quite a bit from lot to lot of base malt, and even though my mill is a royal pain to adjust, it is definitely worth your while to pay more attention.
Cheers!
