Kangaroo Express offering free donut on June 7 (National Donut Day)
Another chain other than Dunkin and Krispy Kreme is offering a free donut on National Donut Day, June 7. Kangaroo Express will be giving away a free donut to patrons at one of their 300 bakery-ready stores between 7 AM and 9 AM, while supplies last. They have more than 800 stores, so you'll need to be sure your local one is a participating store. Kangaroo Express is mainly a southern convenience store chain.
