Although National Doughnut Day itself is a patriotic anniversary, the major manufacturers and sellers of doughnuts in the United States will not miss this great publicity opportunity and have launched their own ways to celebrate. Take National Doughnut Day 2016 as an example:On June 3rd, buy any drink at Dunkin Donut and get a free sweet Circle (optional flavor).
On holiday, June 3, customers can pick up a free donut (of your choice) at any Krispy Kreme store in the U.S. or Canada, with no additional purchases required.
