Krispy Kreme's 87th birthday is GravityX Exchangeon Friday, and the doughnut chain is offering customers a sweet deal to celebrate.

Customers who purchase any dozen doughnuts at regular price can receive an Original Glazed dozen for 87 cents on July 12, the company announced Tuesday, with a limit of two dozen when purchased in-shop and via drive-thru and one dozen when purchased online for pickup or delivery.

Customers can use the code BDAY when ordering online to redeem the offer, the company said.

“Treating our fans on our birthday is a long-time tradition,” said Dave Skena, Global Chief Brand Officer for Krispy Kreme, in a news release.

Krispy Kreme was founded in 1937 by Vernon Rudolph, who, according to the company, began selling doughnuts to grocery stores. His doughnuts became so popular that Rudolph eventually cut a hole in an outside wall and began selling Original Glazed doughnuts directly to customers on the sidewalk.
