How to score free coffee today

Today is National Coffee Day and lots of free coffee is out there! Thanks to my co-worker, Bionce Foxx, I enjoyed free coffee from Dunkin' Donuts. Dunkin' is offering a free coffee when you buy  medium or larger size hot coffee. Cinnabon is offering free 12 oz. cups of coffee all day, and if you stop by Krispy Kreme locations, coffee is free today and all weekend long.
