June 7 is National Doughnut Day. It’s a sweet holiday worth celebrating, especially since you can score deals and discounts on doughnuts at several national chains.

The first Friday in June has been celebrated as National Donut Day since 1938 when it was established by the Salvation Army as a way to honor the organization’s Donut Lassies, women who traveled to France to serve donuts and snacks to soldiers during World War I.

Here’s where to go for some of the best giveaways:

Dunkin’

Customers at Dukin’ can receive free classic donut of their choice with the purchase of any beverage. This deal is only available on June 7, while supplies last. You can see more in Dunkin’s summer menu here.

Krispy Kreme

Guests at Krispy Kreme can receive any favorite doughnut of their choice for free, no purchase necessary, though some limited-edition flavors may be excluded. Customers can also receive a free dozen original glazed doughnuts with the purchase of any dozen doughnuts.
