Suburban Propane review: Propane price

I called to request a delivery of Propane Gas to my residence that has a 250-gallon Suburban tank. They didn't tell me about the price per gallon and I was ok with plus or minus a couple of cents. But after the delivery, I discovered from the bill on the door that they charged me an outrageous amount of $4.699 per gallon. That was Friday and now it's Saturday and they are closed.
