Acaully I was shop owner for about 2 yrs, Great planes and horizon both have a standard 20 dollar a case hasmat charge. that was to any shop who ordered through them, PM or CP wouldn't sell direct since I couldn't do enough volume. I did finaly find a distributor within 100 miles and would haul the stuff and was able to sell PM at 12 bucks a gallon making a whole 1.89 for a gallon, being a cali doesn't have anything to do with the prices. If you buy in bulk they'll save alittle off, the guy sell it for 9.5, I'd sure like to know how he did it. You'd have to sell a whole lot of fuel to get that kinda of price. Hell for me somethimes it was cheaper to just buy from tower. Water under the bridge since I sold the place. Like I've said before. support your LHS or it won't be there
