Dunkin' Donuts is giving 12 lucky customers the chance of a lifetime - to win free Dunkin' for a whole year! The event ends on Saturday, March 17th so you have to hurry, but entering couldn't be easier.

To celebrate the release of their new St. Patrick's day, brownie-batter donut, Dunkin' wants you to show how you get festive on the holiday! Take a pic (with a Dunkin' coffee & donut of course) and show them your spirit on Twitter and Instagram. Use the hashtags #Sweepstakes and #DDLuckyDozen to enter and then cross your fingers!

One special prize winner will even get a tour of the Dunkin' Factory & a chance to mix their own flavor. Sounds like a dream.
