Well, let's do a little math. If you sign up with Upromise, Mobil will pay 1¢ for each gallon of gas you buy into a college savings account. I drive about 10,000 miles per year, and my car gets about 25mpg. That means I buy about 400 gallons of gas per year. That means Mobil would pay 400¢ per year. Wow, $4, that's really going to help send my kids to college!
This program must cost Mobil a fortune, because they are advertising it everywhere. No doubt there is positive PR value to the message "we're helping you save for your kids' college", but don't people do the math?
