I go to a "propane dealer". That's all they do. They deliver to homes with propane service, plus fill up campers and locals with barbecue grills.
They charge $0.50 a pound if not empty. $10 for a fillup. The new tanks may be called "20 pounders", but they actually only hold 18# because of safety concerns. So, 18# IS filled all the way up.
