For new customers only, Groupon offers a voucher for a Papa John's Large 5-Topping Pizza bundled with your choice of Breadsticks or Garlic Knots for $12.99. Coupon code "CHZZY" makes it free. That's a savings of at least $27 and the best deal we've ever seen for a Papa John's pizza with no minimum purchase required. (For further comparison, we saw a 5-topping pizza for $10 in April.) The voucher expires 120 days after purchase.

Note: The coupon also takes $15 off Groupon's other Papa John's deals on the page.
