Here's how it works:
The logic here is simple: Krispy Kreme's been around for a long time -- 80 years, in fact! Its first location opened for business July 13, 1937, and the chain started selling its signature sugary delight, the "Original Glazed" donut, the following day, July 14. So today, Friday, July 14, 2017, Krispy Kreme will blow out its birthday celebration at all locations in the United States and Canada buy offering a deal: buy any dozen donuts at Krispy Kreme for regular price, and you can get a second dozen for 80 cents.
It gets better: Shaquille O'Neal, he of basketball and viral-toe fame, is also involved, since he's a Krispy Kreme franchisee. It looks like he spent a fun day making made this kooky video where he surprised Krispy Kreme customers with his magnetic 7'1" presence.
