Better to have little good coffee than a lot of burnt coffee. Right now I'm paying less than $10 for 1 kilo of regular medium roast beans. I buy 3-4 bags a month because I carry my 1.5 liter thermos almost full of coffee every other day for my classes; I like to share it with everyone, which I wouldn't be able to do if I bought specialty coffee, which by the way, I haven't bought since August of last year.
How much coffee is that? 70 ml or more?
