Where can I drop my trade-in box?

Typically it is either shipped by FedEx or UPS. There are usually UPS and FedEx stores and drop boxes in various locations. You can go the UPS and FedEx websites for information as to where these are located as well as ask them how you can get it to them to ship.

If it was mailed to you with a label going to a third party trade in partner company, you need to mail it to them using the shipper mentioned on the label.
