1 per person. No purchase or coupon needed. Just walk in and ask. Check their site to see if your local store is participating. We just got ours and it was sooooo yummy! Happy National Doughnut Day!
We don't have any Krispy Kremes around here anymore...just got back from Dunkin Donuts, Their deal is if you buy a drink, you get a free donut. Not bad, we got 2 Coolattas and a Iced Latte, 3 donuts for $5.00! Plus for some reason, the guy gave us an extra donut!
