On June 4th, participating Dunkin’ Donuts restaurants nationwide will offer all customers a free donut of their choice with the purchase of any beverage (limit one per customer)! The promotion is in celebration of National Donut Day, originally celebrated by the Chicago Salvation Army in 1938 to honor women who served donuts to soldiers in WWI. Also on June 4th, the company will announce the winner of the second annual “Create Dunkin’s Next Donut” contest. What are you waiting for? Get to Dunkies and get your free donut!
