Dunkin' Donuts is selling T-shirts featuring the winning design from its first global T-shirt challenge as one of its holiday merchandise offerings.

The "C is for Coffee" T-shirt is being sold on Shop.DunkinDonuts.com, for $17.99.

Dunkin' launched the T-shirt contest in partnership with the Threadless online creative community in September, on National Coffee Day.

The winner, Phil Jones of Minneapolis, Minn., won $7,000 in cash, a $500 Threadless gift code, and free coffee for a year or $100 in Dunkin’ Donuts merchandise.  

Dunkin' reports that it received more than 1,000 design submissions. 

Dunkin' is also offering limited-time holiday deals, including three pounds of its packaged coffee, or two boxes of its K-Cup packs, for $19.99.

With restaurant chains battling for share of holiday business, Dunkin' is also promoting its restaurants as places for Black Friday shoppers to recharge (some  Dunkin' locations will be open before 5 am that day), and stressing that nearly all of its U.S. locations now offer free, high-speed Wi-Fi.
