Check what price they charge per gallon before filling your tank, so you don't get raped as I did.
I've been to many propane filling stations and the average price per gallon is $2.25 per gallon? (but I just got screwed) filling up my propane tank in Benson Arizona were they charged me $12.82÷2.9
$4.420689655 per gallon.
I've heard of price gouging but this is ridiculous?
