Our local hardware store has been offering $1.00 off a gallon on propane (now $2.15 gal) due to our extreme cold temperatures. Other places quit filling because it is too cold. We have been in the negatives for weeks now (I've seen -20 every day this week on my drive into work and back home)and the deal is, you have to ask for which of the two guys who own the shop have to make the trek across the lot and stand there while filling your tanks. Their supplier has had to refill the bulk tank every day. Good times!
