Context: New Haven-style pizza, locally known as apizza ( , from Neapolitan "’a pizza" (] ) "the pizza"), is a style of Neapolitan pizza common in and around New Haven, Connecticut.

An order is typically made either by telephone or over the internet to the pizza chain, in which the customer can request pizza type, size and other products alongside the pizza, commonly including soft drinks.  Pizzas may be delivered in pizza boxes or delivery bags, and deliveries are made with either an automobile, motorized scooter, or bicycle.  Customers can, depending on the pizza chain, choose to pay online, or in person, with cash, credit or a debit card.  A delivery fee is often charged with what the customer has bought. Seasonality of food refers to the times of year when the harvest or the flavour of a given type food is at its peak.  This is usually the time when the item is the cheapest and the freshest on the market.  The food's peak harvest time usually coincides with when its flavour is at its best.  There are some exceptions; an example being sweet potatoes which are best eaten quite a while after harvest.  It also appeals to people who prefer a low carbon diet that reduces the greenhouse gas emissions resulting from food consumption (Food miles).
