Well at home you get the coffee from somewhere, compare to that? I buy a bag of I think 250g beans for £7.95 (about $10 I suppose, conveniently) and without travel I probably get through at least four bags in a month.

That's much more coffee that Kagi costs than if I was getting it at Starbucks, but it still puts it in perspective I think. (And the coffee tastes much better.)
