Everywhere I have lived seltzer water (straight carbonated water, no minerals, salts, sugars, anything) is pretty common, supermarkets almost always have a section of it. Usually you are looking at $0.50-$0.80 per liter if you buy liter bottles, and a bit cheaper if you buy 2-liter bottles. Pricier than it should be perhaps, but I honestly think I have an addiction to it; I've been drinking carbonated water at home almost exclusively for years. I'm considering getting a professional carbonation setup like a bar might use.
