A large supermarket chain near my abode also runs a convenience store-style gas station in front of the supermarket. They run a thoroughly marketed promotion whereby customers receive a discount for gas based on how much money they spend on groceries.
Having just dropped a serious chunk of change on groceries, I received a fuel coupon for a discount of $0.23/gallon. Nice, I thought. That’s almost four bucks off on my next tank of gas.
