I personally have never ordered more than 'the night before,' so I don't know if Papa John's (who lets youLog In) calls to remind you you made the order. But if they don't, don't you think they should?
I didn't know they let you order it that far in advance. That'd be really handy for parties! But yes, if they don't call, they probably should. I'd hate for someone to forget that they ordered 20 pizzas and then Papa John's shows up with all the pizza and doesn't get paid for them, etc.
