Coffee

I spend about $120 a year on coffee beans. It seems like a lot, but when compared to Starbucks, it’s cheap.

Sizes
Tall (12oz) Grande (16) Venti (20) Cost/oz (avg)
Starbucks[1] $1.40 1.60 1.70 $0.10
Sumatran[2] $0.12 0.16 0.20 $0.01
Kona[3] $0.60 0.80 1.00 $0.05
Starbucks prices vs. Beans

You can have Sumatran for 1/10 the cost, or the greatest coffee for mere mortals, Kona, for 1/2 the cost. And neither tastes like ash.
