If you go to Dunkin Donuts Philadelphia's Facebook page and "Like" it, you'll be able to download their coupon printer and print weekly coupons from their "Fan Zone."
The coupons are available and are good each Monday through Thursday. This week's deal is a free medium hot coffee. The coupons are good in Southeastern Pennsylvania, in Southern New Jersey and in Kent and New Castle Counties in Delaware.
The application allows for fans to print only one coupon per Facebook profile each week.
