welding gases

Hi we are a small car restoration bodyshop & repair garage & I am trying to find out what the most cost effective gas supplier is but it seems that they don't all use same cylinder sizes & boc don't seem to quote capacity in litres [just a lettering system] so comparison is difficult does anyone have any ideas ?BOC seem expensive because of cylinder rental costs
thanks Mike

The large W size bottles from boc and air products pretty much same size. Boc fill pressure 230 bar. Air prod 200bar.
Main thing I discovered is that the prices are not fixed in stone.
If you can get through to the right sales folks they will talk turkey.
I just opened an account at the local Ap stockist and paid the given prices for years. Wasted a lot of money.
