They deregulated our gas a few years ago, you still a have the same company for delivery but now you get to choose who will rip you off for gas you buy. When the price of gas is low you never here of the other companys but when the price is high there are dozens of them coming door to door selling a bargin on a three year contract and then the price goes back down and you get ripped off for three years. Our delivery company varies the price of gas to follow the market and I think on average they are the best bet.
