full bottle of helium - $100 (simi valley)
I have a 200cf bottle of helium. Airgas charges $250 to fill a bottle this size. I need a bottle but I don't need helium. Trade me your empty helium/argon/argon co2/nitrogen bottle and $100 for my full helium bottle. I would also consider less money if your bottle was full of argon or argon co2 mix.
