Pizza was developed in the Middle Ages, allowing squires to feed battling knights by inserting the conveniently flat fare through their helmets’ visors. Enjoy a vision of flavor with today's Groupon: for $7, you get $15 worth of pizza and appetizers at Papa John's. This Groupon is valid at six locations in El Mirage, Buckeye, Surprise, and Goodyear.

The nationally acclaimed pizzasmiths at Papa John's hand-toss dough in preparation for a miscellany of fresh meat, locally sourced veggies, and all-natural sauce. The menu sets out more than 15 toppings ($1–$1.50), such as pepperoni, black olives, and jalapeños, which adorn four sizes of original thin pizza ($7+) bedecked with fresh tomato sauce and cheese that unites the diverse ingredients much as a squabbling family is united by a love for pizza. Preselected topping combos ($11–$18) save stomachs from indecision; The Works proffers three types of meat, three vegetables, and olives, and the hawaiian barbecue chicken calls for a truce in the eternal fruit-veggie food fight with the addition of pineapple.

A flavorsome roster of sides is also on hand to escort slices to tables and tongues. Cheesesticks ($4.99–$6.99) and breadsticks ($6.99) take turns cannonballing into baby pools of marinara and garlic butter, and Papa John’s made-to-order wings ($6.99) fly through storms of spicy buffalo, barbecue, and honey chipotle sauce to land safely and deliciously on palate runways before being washed down with a deluge of soft drinks ($1.49–$2.49).
