When I went to pick up my FREE Papa John's pizzas this weekend, I found this flyer on the couter:
Order online for delivery or carryout at papajohns.com and use promo code 50off.
While you're online (and before you order) register for their My Papa Points program. You can earn points with each order and score FREE PIZZA! I cashed in points for a couple of free pizzas this weekend, and I only order when pizza is B1G1, so it's easy to get free pizza!
