Gas points and rewards at local stores!
I buy Amazon (and other) gift cards to earn gas points at Kroger and Safeway stores.  This also includes Texaco (Kroger/Fred Meyer) and Chevron (Safeway). You earn 2x the rewards. For example, buy a $100 gift card at Safeway.  Safeway or Chevron gives you $200 (20 cents) off your next fill up.  Many times throughout the year, Safeway or Kroger will make the deal even sweeter, with 4x or sometimes even more gas rewards. I get my things I cannot get on Amazon while at Safeway/Kroger.  So I almost always get $1 off a gallon when I fill up my gas tank.
