C.O.D. fuel is simply purchasing heating oil on a delivery to delivery basis. Choosing oil and buying on C.O.D. gives you the flexibility to buy heating oil at the lowest price.
C.O.D. fuel is the same principal as filling up your car at the gas station. Certainly, wth all of the choices of gas stations out there, you wouldn’t want to commit yourself to a long-term contract with only one.
You can buy the amount that you want based on your budget. C.O.D. fuel options give you more flexibility to fit your cash flow into your budget.
