I always thought that gas bottles , thats Argon etc , had to be hired with an agreement , account etc , but I'm seeing references to rent free gas on here ?
So is it possible to have a bottle refilled on a sort of pay as you go basis ?
Try sending a PM to gasman. Can't remember who he works for, but he put me onto someone local to me that supply their gas. 3 year "right of use" on the bottle was something like £35. He might have someone close to you!
