On Wednesday, Krispy Kreme closes the box on its Beat the Pump promotion. The doughnut chain has been offering a dozen doughnuts for the price of a gallon of gas. The promotion has had a good run and will end Wednesday. Wednesday, May 4, you'll be able to grab a dozen doughnuts for only $4.19, the same price as a gallon of gas. You can score the deal in the drive-thru, pickup by ordering, or by ordering on the app. What flavor is your doughnut guilty pleasure?
