Just for prospective - I just got a 350 gal delivery for propane at $.99 per gallon.
Heck, I spent more than you just did when I bought 150 gals of propane last winter. That was when I saw my lowest price at $3.22 (yep - ~$500 for that 150 gallons). If I had locked in at the rate they want this year, I would pay even more (assuming I need to get propane at all - last I checked, I hadn't even used all of that 150 gallons).
