Getting CO2 for a Soda Stream without supporting Soda Stream
I drink a lot of carbonated water and my sister got me a Soda Stream. Very nice gift except I hate the company (political reasons). That's why i never got one in the first place.
My understanding is that i'm supposed to exchange CO2 canisters at licensed vendors to get more but, uh, i don't really want to do that.
Do I have any good options?
Thanks in advance.
