i think it is about $.10 to $.15 lower on average nationwide. But... the diesel that is mentioned here isn't pump diesel. it is ROUGHLY ~20% castor, ~50% kerosene and ~30% ether, and is actually just as expensive as regular glow fuel. (check the price for davis diesel fuel, about $20 for a gallon, $13 for a quart. (not saying pump diesel won't work, but it isn't recommended by davis diesel, which of course sells the recommended fuel!
