I wish I could have your bill! I was recently shocked by my natural gas heating bill at a second home in Virginia. It is Columbia Gas and the bill was $490 for one month! The home has two furnaces but really? We weren't even living there and the heat was set at 70.  (now a lot lower while no one is there)

I think on the contrary, Gas companies are increasing the price of natural gas to make up for losses possibly? If you don't really shop around for a supplier, this type of thing's gonna happen!
