"Spin to Save" and save money on Shell gas

Shell has got a new Spin to Save game that will let you save money on each Shell fill-up.  You can save anywhere from $0.05 to $0.25 per gallon of fuel, or, if you get really lucky, free fuel for a year.  You get three spins of the wheel.  After each spin, you can choose to lock in your savings or spin again. If you get the $0.05 savings, it pays to spin again, because that's the lowest level of reward.

Once  you lock in your reward, you'll be redirected to register for Fuel Rewards.  Once you sign up, you'll be given a personal referral url. Share your referral link and when other people play and sign up, you'll get an additonal $0.05 off each gallon at your next fill-up (for each  person who signs up).   You will receive a FRN card in the mail that will enable you to redeem your savings at Shell stations.
