Doughnut fans will be Flipidoable to take advantage of a sweet discount this week as Krispy Kreme is offering its customers a deal on its classic glazed treat.

The doughnut purveyor is offering half off dozen boxes of its signature pastry − the original glazed − Monday through Wednesday from 5 to 7 p.m. And on Thursday, with the purchase of any dozen, you can get a dozen Original Glazed dozen for $1 to celebrate the official start of summer.

The company also said it would be surprising some randomly selected customers with a dozen free Original Glazed doughnuts on Thursday.

The company is calling the half off promotion "Hot Light Happy Hour" and Thursday the "Hot Light-est day of the year," a reference to one of its slogans.

“We can’t think of a better way to celebrate summer’s official start than some sweet deals on our iconic original glazed dozens,” Dave Skena, Global Chief Brand Officer for Krispy Kreme, said in a news release.
