Any order over $150 (before tip) is considered an extra large (XL) order.
The Grubhub delivery product started off with the intention of facilitating a way for individuals to order food from their favorite places that may not deliver. As Grubhub continues to grow, so do the size of the orders. Instead of individuals ordering while at home, groups of people now order together both at home and in the office. Over the last few years, Grubhub has seen a dramatic increase in these large group orders.
