Got an extra 100 gallon propane tank set for my generator. Set on Monday, finally filled on Thursday and bill arrived today.
I knew it was going to be significant as propane is ~$4.00 a gallon for small tanks, but when I looked at the bottom line and saw $1198.xx, I about shit myself right there in the post office!
A little further investigation revealed that they hadn't yet credited my last payment for heating oil (~$700.00) so the actual bill was around $400 which was about what I expected.
Definitely pressure-tested the ol' cardiovascular system for a minute there...
