Reference information: How does a pick up order work?
http://corporate.seamless.com/faq/how-does-a-pick-up-order-w...
The ordering process is the same as a standard Seamless delivery order – select your starting address (where you’ll be picking the order up from), choose from the restaurants available for pickup, add items to your order from the menu (no need to worry about delivery minimums!), checkout and then go get your food
whats carryout?When ordering pizza, what does carryout mean?
Carryout is the same as to-go. It means that you go to the restaurant, and pick up the food.
It means you pick the pizza up at the store instead of having them deliver it to your house. You can call ahead of time and order it, and they'll have it ready for you when you get there.
