Everyone loves (mostly) free donuts right? Of course they do, which makes Saturday Dec. 12 your lucky day – as long as you enjoy the idea of getting 12 free glazed dough tori from Krispy Kreme. To ensure everyone has their fair shot at what it’s calling #dayofthedozen, the company has created the “World’s Tastiest Coupon,” a video feature donuts rolling under a stream of glaze. That glaze just so happens to make a barcode, and when scanned – either via a print out or the video on your phone – gives the customer a dozen free donuts when you buy a dozen.
