Whether it's debuting festive holiday cups or rolling out new holiday pastries, Dunkin' Donuts has really been aiming to impress customers lately. Now, the coffee chain is running two sweepstakes with crazy big prizes at once—and literally giving away coffee left and right.

For today only, Dunkin' fans have the chance to win a year's supply of espresso drinks—like the new macchiato—via Twitter. Part of a celebration for National Espresso Day, the sweepstakes includes four trivia questions that the brand will tweet throughout the day. To enter, just tweet your answer to the question using #DDEspresso and #Sweepstakes. 

From there, you'll get the chance to win a $100 DD gift card. The best part is that one grand prize winner will walk away with a year's worth of Dunkin' Donuts espresso drinks. To be eligible, you must have a public Twitter account and be following Dunkin' on Twitter.

And, as if free coffee for 365 days wasn't enough, DD is also launching a "Joy of Coffee" campaign that gives customers the chance to take home plane tickets and gift cards. By sharing a photo of your holiday cup using #DDCoffeeJoy and #Contest on Twitter, Facebook, Instagram, and Vine, you'll get the chance to be one of 12 winners of round-trip JetBlue travel vouchers (worth up to $298) or one of 50 who receive $10 Dunkin' gift cards. The photo-sharing contest launches Tuesday, November 24 and runs through Saturday, December 5. Before you start blasting your social media feeds with holiday cup propaganda, know that you can only enter once—no matter the platform.
