Sure, the weather outside might be getting frightful, but not everything has to be terrible during December—especially since Dunkin' Donuts is giving away free coffee. Yes, you read that correctly. You can get free Dunkin' Donuts coffee this holiday season. For one weekday between December 12 and 23, nearly 30 Dunkin' Donuts stores will hand out free coffee to 500 customers as part of the company's so-called "Brewing Joy" holiday celebrations. According to a press release, the free coffee promotion begins on December 12 at two stores in Chicago, Illinois, then moves to cities around the country including Philadelphia, Pennsylvania on December 13; Nashville, Tennessee on December 14 and 15; and Dunkin' Donuts' home turf of Boston, Massachusetts on December 20. The locations of the specific participating stores will be announced closer to the date on the Dunkin' Donuts blog. 

All you have to do to get a free medium hot coffee is show up at the store—before they run out. But if you don't live near a Dunkin' Donuts that's giving away free coffee this season, or you miss the promotion entirely or are just overwhelmed by the idea of waiting in a long line for a free coffee, don't worry. You still have a chance to win free Dunkin' Donuts coffee.

The company is also running an Instagram contest, using the hashtag #DDCoffeeJoySweepstakes. Starting today, December 5, and lasting until December 23, Dunkin' Donuts will provide a weekly holiday theme. Folks who want the chance to win free Dunkin' Donuts coffee can post pictures or videos to Instagram with the hashtag to show "how Dunkin' coffee plays a part in this holiday activity." This week's theme is "pretty lights," and at the end of the week, five entrants will win a month's worth of Dunkin' Donuts coffee and one grand prize winner will get a year's supply of the good stuff. So if you want to win, it's probably time to chug what's left of your morning coffee and start snapping away.
