Today’s National Groupon Deal is a punch-card for eight Quizno’s Subs for only $26. That’s only $3.25 per sub! This is a national deal, so it is valid anywhere. It looks like once you get your certificate, you’ll bring it to your favorite Quizno’s location and they will give you the punch-card. This is a fantastic deal if you are a Quizno’s eater – especially since the punch-card doesn’t expire!
