Whenever you go to a Dunkin Donut store and buy anything ask for the receipt. Follow the instructions to get your free donut. On your next visit oreder a large coffee and ask for whatever donut you want. When it’s time to pay just hand them the money for the coffee and the old receipt and you will get a free donut.
Deb and I go to our local store probably 6 times a week so we get six donuts a week and sometimes more because we either go twice in one day and also because they know us so well they often give us two donuts instead of just one and they even give us back more than one receipt so that gets us extra donuts.
I have extra large zip lock bags that must hold 6 donuts each and there are at least 6 bags at all times in both freezers.
My favorite is any donut that is glazed.
