25¢ Off Per Gallon on Your Next Fill-Up at a Participating Shell Station (Up to 20 Gallons) when you join their Fuel Rewards Program. Over 100,000 of these FREE Groupons have already been sold. I’ve been using the 20¢ off per gallon Jewel promotion, but heck, that’s bound to end and if you don’t have a Jewel near you, grab this baby! As soon as you join in the Fuel Rewards program, you’ll get instant Gold Status and immediately save 5¢/gallon on every fill-up at any participating Shell station as long as you maintain active Gold Status. Simply swipe your Fuel Rewards card or enter your Alt ID number before filling up.
