Houston, Texas-based Shipley Do-Nuts is giving away its famous glazed do-nuts for free with any purchase in honor of National Donut Day on Friday, June 7 at all 350-plus locations, while supplies last.

To redeem the offer, guests can simply visit their local Shipley shop or order online with code DONUTDAY24. To sweeten the deal, a dozen guests who visit Shipley on National Donut Day and scan their Do-Happy loyalty app will win a year’s worth of free donuts.

Founded in 1936 in Houston, Shipley Do-Nuts is known for its signature glazed do-nuts with a lighter, fluffier texture, hand-cut into their iconic hexagon shape and carefully glazed to sweet perfection. Shipley also offers a wide variety of fresh iced, filled and cake do-nuts, plus savory kolaches, hot and cold brew coffee and more.

“Shipley’s legacy was built on our fresh glazed do-nuts, and they are still our most popular variety to this day,” says Shipley Do-Nuts chief marketing officer Donna Josephson. “We can't think of a more delicious way to celebrate National Donut Day than by rewarding our fans and new guests with the do-nut that started it all.”
