Pay $0.80-$1.60 Per Gallon: Carpool

You can cut your gas bills in half, right now. Share your trip to work with one other person and split the bill. That's like paying $1.60 for gas that costs $3.20 at the pump. (It's been a decade sine the actual pump price hovered in the $1.60-per-gallon range.) With a full car of four people, the cost per gallon is just $0.80! Now that sounds like real savings.
