Amerigas billing is in cubic feet to hide the real HIGH cost of their Propane.
After you convert cubic feet to gallons, then you find the real price.
I have been with 4 different propane company's. All but Amerigas give you the price per Gallons. After converting my bill to gallons. I have found that Amerigas is .90 to 1.00 a gallon higher than any other Propane company in my Area. I will be looking for another local company.
