BP has a promotion starting today called Thank You Days where you can get a $10 BP gift card after your 5th fill-up of 8 gallons or more. At $3 a gallon and assuming you stop at 8 gallons per fill-up, this will save you 25 cents per gallon. Not bad, considering you can still use your credit card and get rewards. I already get 5% cash back on gas with the PenFed Platinum Cashback Rewards card.
The program begins on 12/1/10 and ends on 3/1/11. All qualifying purchases must be completed between 12/1/10 and 3/1/11, or when Loyalty Card supplies are exhausted, whichever occurs first. […] $10 BP REWARD CARDS EXPIRE ON 9/6/11. Offer not valid in New Jersey. […] Limit three (3) $10 BP Reward Cards per person and/or email address per household.
You do have to track some things online. Thanks to reader Drew for the tip.
