Does anyone buy thier gas from a wholesaler? I'm trying to figure out if it's worth the price of the storage tank and what the regulations are. At these gas prices it might pay for itself. I'm thinking of the kind of deal most farmers and golf course grounds maintenace buildings have, a 250 gal or so tank (i'm guessing at the size, they may be smaller or bigger)that is up on a 8 foot or so frame. The local farm bureau (or other wholesaler) comes by once in a while to fill it up. Thier prices are usually cheaper. Anyone tried this??
