I don't know why a donut and coffee always sounds good to me? I honestly wish it didn't, but oh well, let's not fight it....especially when it's free. Dunkin' Donuts has a rewards program called Dunkin' Perks (how witty). When you enroll in the free program, you will receive a coupon for a free medium beverage of your choice which includes any iced or hot coffee, tea or latte, hot chocolate or Coolata®. All cooler beverages are excluded. PLUS, you will get a free beverage coupon your birthday. Enroll HERE.
