We got our bill on Christmas Eve. . . $205. That was an actual reading. The thing is that we keep our house at 64 in the daytime and 62 at night. We also have a gas stove and gas dryer, but in the months when those are the ONLY things we have using gas, our bill is always flat rate, which is $13.00.
We're hoping for a warm up!
A few years ago we had HUGE bills all winter. When April came, we had a big credit on our bill and didn't have a bill at all until November! We never got any reason, either. Nothing said "estimated" or anything.
