This winter, my supplier is charging 1.69/gal if you pay up front for a minimum of 500 gallons. That price includes a .03/gal discount for being on a scheduled delivery as opposed to calling them up for a delivery whenever your tank gets low. It also includes a .03/gal discount for cash payment. My 500 gallon tank is leased. If I owned the tank, the price would go down another .05/gallon.
