I hope some of you folks are heating with propane and don't whine your tank runs out and it's upward of $7.50 a gallon, where it was $1.40 a gallon just months ago. In fact, it's what the market value is. I'm sure you'd smile when your 500 gallon tank get filled to 80% and costs $3,000.00. But, you'd have a choice, right? It's just demand... right? In my area, they are limiting fills to 100 gallons, but why should they? They should just sell it to a few who maybe install tandem 1000 gallon tanks and the rest can, well, pay whatever to get what they want. I doubt anyone here would like to be taken advantage because of the "market price".
