A quality 2 lb bag from a well respected roaster that ethically sources their coffee is $37 and is pre ground so you don't even need to buy a grinder. It will make approximately 64 8-oz cups of coffee. That is less than 60 cents a cup.

What are you talking about, expensive?

If you want a recommendation, I love Mad Priest Coffee roasters based out of Tennessee and ship at a decent price.
