Krispy Kreme's March Madness promo gives new meaning to Sweet 16

When it comes to the NCAA March Madness basketball tournament, brackets are either busted or booming. So one brand came up with a way to sweeten the experience for everyone.

Krispy Kreme announced on Thursday that through Sunday, March 27 all guests who bring in their bracket -- whether it's on paper or an app -- will receive a free Original Glazed doughnut each day they do so.

Customers who join the confectioner's rewards program can also get a dozen Original Glazed doughnuts for just $1 with the purchase of any regularly priced dozen through Monday, April 4.

The offer is valid in shop, drive thru and online with the Krispy Kreme app.
