I filled up 2 weeks ago and paid $2.159. I've filled the tank twice since then and it rose to $2.319 and then $2.419. Slowly but surely, I'm going to see my Shell bill creeping up. Luckily, Shell came out with a promotion two years ago, and if you buy gas at a Shell station and use their MasterCard, you get 5% off your gas purchases. It's helped the bills a little bit. You can be that they're not giving that deal any longer!!
