Haha not matter what it costs to break my contract I would never do it. My oxygen cost is 68 cents a 100 cf. Thats 6.80 for a 1000 cubic foot of product. It would cost me less then 30 bucks to fill a liquid oxygen tank if I wanted to. I use more oxygen in a week then any scrap yard in Saint Louis. I just live in an area that sucks for propane pricing apparently. When i first got here I called everyone and there mother to get propane ameri-gas is always the cheapest and praxair told me they would match there price. Which I though was outrageous at that time. Apparently propane is just plain expensive where I am at. I also had to use 435 propane's because I had to have a permit from the fire department to have any tank bigger then that. There was no way I would be able to get one because I was mobile always moving where I was needed they wanted a pad poured and a permanent location.
