Pizza is a perfect product for large groups. If you're having a party, it's much easier to order five different pizzas for every taste than argue about who wants sushi, who wants wok and who wants burgers. Large delivery orders can get large discounts, because delivering five pizzas to one place is cheaper than delivering them one by one to five different places. We are going to make a convenient build-your-own combo interface, both on the website and in the app. Our customers will see that the more you order at once, the bigger the discount.
