I own a pizzeria, and we have a very extensive toppings menu. We want to run special deals at a discounted rate, such as two pizzas, a large salad and a 2-liter for a certain discounted price. I'm having trouble figuring out how to add this specialty "group" of items in where all 4 items have to be selected before you can proceed with the purchase. In my attempts, I was able to get the pricing set, but you could pick or choose 1, 2, 3 or all 4 before purchase. What am I missing?
