If you are in the Chicagoland area, this is a good one! Head over to the My BP Station giveaway page to get a code good for $.50 off each gallon for one fill-up at BP! This offer is good for the first 100,000 people only, so go over and get yours. It looks like there are 80,000 left, though. You have a bit of time. 🙂
(Thanks Mashup Mom!)
