Just discovered an E85 seller in Hillsboro/Cornelius and figure I'd share -
Thunderbolt Racing Fuel.
I contacted them and was quoted $2.99/g + $15 jug fee (fee is waived on next order and jug is brought back) for their 5 gallon jugs. Not sure if the price is the same for a 55 gallon drum. Nonetheless, they should be closer than Jay's Garage if you live nearby.
