Charlie’s Pizza orders all of its pepperoni, olives, anchovies, and mozzarella cheese to be shipped directly from Italy. An American distributor stops every four weeks to take orders.

Charlie’s prides itself on offering only the best quality ingredientsand a high level of service, so it wants to ensure a 98 percent probability of not stocking out on pepperoni.
