Dunkin Donuts: Free Donut on National Donut Day 2012 on Friday, June 1 (purchase required)

Just like Krispy Kreme, you can get a free doughnut/donut at Dunkin Donuts on Friday, June 1, also known as "National Donut Day".  However, to score your free donut at Dunkin, you'll need to make a beverage purchase to qualify for the free donut offer.

They have a "while supplies last" caveat, so do get there early.

Are you planning to visit both Krispy Kreme and Dunkin to get your freebies?  Let me know in a comment!
