It all depends on how much propane you use and what it's used for. Cooking and Hot Water rates are different than Heating rates. Some companies offer cheaper rates if you own the tank, like .10 under the normal rates. Some gas offer $2.40/gal on Heating rates on 75gal or more if you receive gas every month. If you own the tank that rate is $2.30. I've had ppl call and tell me that Suburban has offered them rates as low as $2.09, but little do they know when they sign a contract with them it's for 5 years!
