In my area you have to order at least 1000 gallons and order it a least once a month to get a "good" price on #2 diesel. I also fuel my Dodge Cummins from the same skid tank so I need to run road fuel. I have had fuel delivered in the past, ag and road fuel, and haven't been impressed with the qualilty of the fuel delivered.
I live in MD and work in VA, I can pick up fuel much cheaper in VA. I can currently buy #2 fuel at my local place in MD for 2.359 per gallon, if I have 1000 gallons of #2 delivered to my place it would be around 2.29 per gallon. The local distributors take the "rack" price then add the MD state tax, .25 per gallon, and the fed tax, .25 per gallon, and add .25 per gallon on top of that. I can buy #2 fuel in VA on my way home from work for around 2.119. I fill up my barrels and a few jerry cans when I fuel my truck and bring it home and dump it in my tank and I am good to guy for a couple of months.
I can also control the quality of fuel in my skid tank by buying from a good source and filtering it when I load it in my tank. Some of the fuel that is delivered around here for ag and home heating use is not the same quality that you would find at a busy station.
Ask my wife, she will tell you lot's of stories. I will spend $ driving around to save $ on fuel/gas /forums/images/graemlins/smirk.gif. I will also drive 20 miles out of my way to avoid 5 miles of traffic /forums/images/graemlins/grin.gif but that is another story.
