Krispy Kreme will sell a second dozen Original Glazed doughnuts for 13 cents on Friday, November 13, when you buy any dozen at regular price. The offer is available for one day at participating U.S. shops, while supplies last.

The first box can be Original Glazed or another dozen that your shop sells at regular price. The discounted box is always Original Glazed. That gets you 24 doughnuts for the price of your first dozen plus 13 cents, before any applicable tax or fees. Krispy Kreme limits the deal to one discounted dozen per guest, so buying another full-price box won’t unlock a second 13-cent box for the same person.

How to get the second dozen

Ask for the offer at the shop. For pickup or delivery ordered through the Krispy Kreme app or website, use promo code 13 at checkout. If you’re ordering online, look for the discount on the Original Glazed box before placing the order. Compare the final pickup and delivery totals if you’re choosing between them.

Krispy Kreme announced the promotion Thursday for World Kindness Day. Its offer announcement applies to participating shops. Use the Krispy Kreme shop finder to check the nearest shop’s hours and confirm it’s participating before making a special trip.
