I am curious about how much a coffee machine really costs. I don't think it can be that much to merit getting rid of it. People that try to save a few pennies usually waste much more elsewhere...
Coffee - not as familiar with the economics of coffee, but of course dedicated machines will end up costing somewhat less than going directly to starbucks.
And most Cokes in a convenience store are now $1.50 or more, at least where I live.
