National Doughnut Day is happening this Friday, June 5th! So Dunkin' is celebrating this Friday by giving free classic doughnuts when you buy any beverage at a Dunkin' location or order on mobile.
On Saturday and Sunday you can order a minimum of $10 through Grubhub and get a free half dozen doughnuts.
You can also enter their "canDOUGHdates" campaign.
Share your slogan on Instagram with the hashtag #DunkinDonutPartySweepstakes from Wednesday-Friday and you might win free doughnuts for a year.
