When you buy a dozen doughnuts at participating Krispy Kreme doughnut shops, you can get a dozen free gift tags. These tags are also coupons, which the recipients can redeem for free coffee and doughnuts.
The coupons available at participating locations while supplies last. And there's a limit of two coupon packs per customer, per transaction.
This offer is good through Dec. 30, 2012.
