I am telling you, you need to listen to me. First, Monday needs to be "Your first TWO Toppings Free" and Tuesday needs to be "Two for Tuesday" meaning buy two pizzas get two free. You obviously have limited window space so you need to rotate the advertisement signs each day. Make sure you get the signs professionally done and do not hand write them.

Give these two promos a try and it will build momentum. Trust me, I am kind of a marketer.
