Krispy Kreme is commemorating National Doughnut Day on Friday with a freebie.

Go to a participating Krispy Kreme shop in the U.S. or Canada and you can get one free doughnut of any variety, not just the usual free Original Glazed.

The offer is good Friday only, no purchase is necessary and you can only get one free doughnut per customer, according to the chain’s website and Facebook page.
