Individual pizzas only per credit, plus drink and dessert (and appetizer if you're on deluxe). You can order the signature pizzas or the basic pizza but if you want to "add" toppings to the basic there is a charge for the toppings.
They used to allow combining credits for larger pizzas but don't anymore, apparently. And they don't allow sharing the individual pizzas on
DDP so you can't use 1 credit to feed 2 or more people.
Kids 3-9 on DDP must order from the children's menu.
