Locking surrounded by on a gas bill? I just get something from my heating company (NSTAR) just about locking...

I just get something from my heating company (NSTAR) just about locking in my price per therm for the gas supply charge portion of my gas bill for the winter heat season. They offer a fixed price of 0.9999 per therm. Currently it is 0.9799. Any proposal about this, we adjectives know heating apartments is gonna be doomed to failure like closing year?. If I can save anything it will be a back???
Answers:    I would recommend locking in to the fixed price situation. I checked my bills from ending winter (Boston, MA), and the cost was 1.19347 per therm. The difference between .979 and .999 is minuscule.
Only approach to get an model is if you have bills from end year to see how much the cost increased during the winter months.
