It would almost be too good to be true, but if the 16" cheese pizza ($17.99) only counts as 1 CS credit, that one credit would be enough food for my young family for lunch. Left over slices could just go in the fridge in our studio. So, has anyone successfully done this or will it work? Will the credit cover the whole pizza or just the slices? Can you add toppings for no extra cost? What is their policy on that?
