Friday, June 3, is National Donut Day, and Dunkin’ Donuts and Cumberland Farms have special deals. Buy any beverage at Dunkin’ Donuts and get a free doughnut of your choice. Purchase a coffee or Chill Zone drink at any new concept Cumberland Farms store, (find locations at CumberlandFarms.com) between 5 and 10 a.m. and get a donut on the house. (Both offers while supplies last.)
