Dunkin' Donuts is also inviting fans to celebrate Halloween by dressing up their cup for a chance to win a $100 Dunkin' Donuts Card. Dunkin' Donuts is introducing its first-ever #DresseDD Twitter and Instagram Contest. Today through October 29, fans are encouraged to tweet @DunkinDonuts on Twitter or Instagram photos of their Dunkin' Donuts cups cloaked in a creative Halloween costume, using the special hashtag #DresseDD. On Halloween day, October 31, Dunkin' Donuts will share the photos of five winners selected for their creativity and Halloween spirit, who will each win a $100 Dunkin' Donuts Card to help keep running with Dunkin' Donuts coffee, donuts, sandwiches and baked goods long after the holiday.
