I love Papa John's Pizza. You can actually sign up online to be able to do orders that way, which I love because they email me specials that you can't get by ordering on the phone.
I recently got an email from them advertising for a special Labor Day deal you can get 3 Large pizzas for $21 which is an awesome deal. They also do different little specials where you can get free breadsticks or chicken tenders. It's an awesome service that Papa John's has and I recommend it for anyone who doesn't have time to look up the number everytime you get a craving for pizza. Their menu is spectactular as well, as you can find anything, quick and simple.
The food is excellent as well.
