One way to save on gas

I already have a Speedpass, but for those that don't ExxonMobil is promoting its wand-waving payment system with a 5-cent per gallon discount to new members for 90 days beginning June 1. The maximum that ExxonMobil will let you save is $20. If you happen to live in one of the five states where it is prohibited by law to "give away" gas (New Jersey, Louisiana, Florida, North Carolina and South Carolina) then you will get a $20 credit on your new Speedpass account. Better than a kick in the rear.
