Does anyone know where to drop the little green ones for recycle? I use them sometimes for day outings, but always bring them home and I am starting to have a little collection of them.
The exchange program is pretty good in my mind. The place where I got mine is $22.00 to exchange the tank and get a full one. The first one was $60.00 full. If you can find a place to fill yours for $15.00 then I guess that is a better deal, but not as convenient. With an exchange one you also dont have to worry about your tank expiring.
