Are you buying at the pump? We don't have off road at the station around here. We have to put in a tank at home and have it delivered. By that time it's cheaper to buy on road and apply for the refund at tax time. That guarantees fresh, clean fuel at market price. On road price here varies 40 cents a gal within 10 miles. Right now I'm paying $2.39 on road. 5 miles south it's $2.80+ .
