This isn't available in all states as my area doesn't have Walmart gas stations and I have never heard of Murphy gas station. I participate in my grocery store's Stop and Shop gas rewards programs which gives points for each dollar you spend and you can get up to $2.20 off a gallon if you save up. Occasionally they offer "extra ways to get points" if you buy certain things in the store.
