Once upon a time, you could take your gas bottle anywhere to exchange, and I thought, that wow the prices aught to have dropped in Jan 2015, that I might get it cheaper somewhere, but NO, gas bottle refil is as expensive as ever, I emailed Supagas, and they actually responded, so, even tho the prices are still not lowered, "HEY, they emailed me back, so they get my service" Thanks for emailing me back guys!
