Potbelly Sandwich Shop offers the recipient of this item 3 Free Sandwich Tickets to be used at any location for an original or skinny sandwich. Potbelly Sandwich Shop began in 1977 as a small antique store run by a nice young couple. Despite the fast-paced, never-a-dull-moment world of antique dealing, the couple decided to bolster their business by making sandwiches for their customers. What began as a lark, turned out to be a stroke of genius. Soon, people who couldn't care less about vintage glass doorknobs were stopping by to enjoy special sandwiches and homemade desserts in this unusual atmosphere.
