I started burning coal on February 13, 2014, moving away from kerosene.
I have saved approximately $301.97 from then until today, March 22, 2014 (38 days). (yes. I'm a spreadsheet nut)
Had I been smart enough and fortunate enough to find my stove at the start of this heating season, I would have saved $1,353.56 this season.
Makes me happy and sad. I'm saving from here. All hail coal!!!
