If you sign up to their website they email you a free voucher for 1 original glazed doughnut. So presumabely you just print it off, cut it out and take it to the store? Seems a bit weird as there's no bar code on it or anything and you could just continuously keep printing them off the email every time you wanted a doughnut? Obviously, you couldn't use them all at the same time, but you could easily keep going back every few days, or go to different stores.
