I just did some rough calculations. At the going rate of $200 per cord: My 12 free cords saved me $2400. And it cost me $4000 in oil last year to heat the house. If the 12 cords last me 3 years, that's up to $12,000 in oil savings. For a total savings of $15,000. I have near $15,000 sitting in my yard right now. Anyone else add up their savings?
