All November long drivers who purchase gas at a Speedway Gas Station and use their Speedy Rewards Card with be rewarded with 3¢ off of every gallon. That may not seem like much, but it’s free savings. At Kroger Gas Stations you can save up to 10¢ per gallon, but that’s only if you purchase at least $100 in groceries first. And with gas prices going back up, you can use all the help you can get.
