Krispy Kreme starts 'Day of the Dozens' early for rewards members. How the donut deal works.

Time to plan for a sweet deal: Krispy Kreme Doughnuts is bringing back its annual "Day of the Dozens" Sunday.

With the purchase of any dozen doughnuts at regular price Sunday, get a dozen of the chain’s Original Glazed Doughnuts for $1. The deal day is a play on the date Dec. 12.
