On April 1, trust no one…except us. 😉 While everyone else is busy pulling pranks this April Fools' Day, we here at Dunkin’® are skipping the tricks and serving up something real: a free coffee to fuel you on the one day you might need it the most. On Tuesday, April 1, we’re giving away one million FREE Hot or Iced Coffees or Cold Brews of any size* to Dunkin’ Rewards members, while supplies last.
