If I am currently paying $1 per bottle of store bought (2L) club soda, and I get make 2 L of water using Sodastream for $0.80, I will make my money back in no time (considering I drink 3+ liter a day).
Sure it might be cheaper to go food grade and do it that way, but I am more than happy saving even a smaller amount of money, because it adds up quick.
