Not so much dealing with expansion but seemed a good place to put it.

On Cue uses an app call Fuel Forward which is free. You use it to pay at pump or inside instead of having to physically use your card. What is nice is that it gives you .05 cents off per gallon. Even better is they run specials. On July 4th, it was an additional .17 cents per gallon for a total of .22cents per gallon off. Was limited to 30 gallons. Nice little savings. My wife and I both went and filled up our cars that day.
