Coffee used to be alot cheaper. Pop was too when we were kids. They are only water with additives but at least pop and coffee can't be found running right out of your kitchen faucet. At work we had an RO system just 10 feet away from a machine with bottled water and a few still bought the damn water at $1.25 a bottle. At least the coffee crowd used the RO water to make theirs. Kinda explains why the country has so many problems.
I make my coffee at home mostly. Gatorade too from a can in Summer. Paying for bottled water short of a dire emergency is just kinda like paying for air. It just ain't right.
