"One and done." That's what a restaurant manager told us about his experience with daily deal sites a la Groupon and LivingSocial where a special offer brings customers through the doors who then never return as they follow more discounts to other places.
A new national deal offered by Quiznos through Groupon is looking to break through the cherry-picker mentality and get consumers coming back for more subs and salads. Here's the deal: For $25, consumers get a punch card for eight sandwiches or salads, roughly $50 worth of grub. More than half of Quiznos' franchisee stores will be participating.

"I don't think either Groupon or Quiznos was interested in pursuing flash-in-the-pan," Michael Roper, Quiznos' chief operating officer, told Crain's Chicago Business. "We wanted an opportunity to generate new regular customers. For them, repeat business is critically important. It gives their business value if they can create more value for a customer like us."
