UNDATED - Pick up that cup of joe because September 29 is National Coffee Day.
Several chains are offering free coffee Sunday:
- Starbucks will you a taste of its Ethiopia coffee
- Krispy Kreme's select locations in D.C., Rockville and Alexandria will give away any 12 oz. mocha, latter or iced coffee (including Pumpkin Spice Latte) for $1.
- You can treat yourself to a free small hot or iced Dunkin' Donuts coffee at participating restaurants. The catch? Show the Dunkin' Mobile App on either iPhone or Android.
