You missed the Black Friday and Cyber Monday sales. But keep looking, the online places might have a "after Christmas" bargain. Yep, Cascade is low in cost, Centennial isn't bad either.
I am a cost conscious person as well...wife, kids and bills to prove it. When I buy, I may get a lb. of cascade, a lb. of centennial and I will throw in a 8 oz. bag of something I would really like to try. The costs balance out that way, plus I am still able to experiment while making goods beers all of the while.
A beverage that I enjoy, as cost efficiently as possible...that's my bag.
