Any Facebook user who becomes a “fan” of the official Papa John’s page will receive an online redemption code for a free medium pizza with any online pizza order.

“For our customers who already love Papa John’s, a free pizza is simply our way of saying thank you for their loyalty,” says Jim Ensign, Papa John’s vice president, marketing communications. “And for those people who aren’t as familiar with Papa John’s and our belief that better ingredients make a better pizza, we invite them to see–and taste–the difference with this special offer.”

In addition to offering a free pizza to its new fans, Papa John’s will provide the same offer to the more than 10,000 Facebook users who are already fans of the brand. And while the free medium pizza with any online pizza order can only be redeemed once, Papa John’s Facebook fans should expect to receive regular exclusive offers.

Note: This Facebook offer is available only in the US.
