Move to Cuba
Are you spending too much money on propane?
If so I suggest moving to Cuba. Cuba has a mild climate except they have communism there. And we all know what happens to communists: They get killed dead.
Business is business and any successful businessman knows the rules of free enterprise: Charge as much as the traffic will bear.
Any graduate of a business college would tell you that. Even Ayn Rand.
If you don't like to pay high prices for propane, then don't buy it.
It's that simple.
