Papa Johns is a great pizza business. I think the fact that they add garlic and sauce dip with your pizza really bought me, I love dipping the crust in something. Their bread sticks are good too if you're looking for a good addition. They're not very expensive when it comes to pizza. If you want cheap poorly made pizza try Pizza Hut.
Personally I like Donatos more, but because they are so local I often buy from these guys.
