Get a free 'I Voted' Krispy Kreme doughnut on Election Day

Doughnut lovers can get a free one at Krispy Kreme on Election Day, but there is a catch.

Krispy Kreme Doughnuts on Thursday announced any guest wearing a sticker indicating he or she voted will receive one free doughnut of choice on Nov. 8 at participating U.S. shops.

The delicious choice is only available to those guests wearing a voting sticker on Election Day. No coupon is necessary. There are some locations that are not participating, which Krispy Kreme lists here.
