Your U.S. address details the location of our warehouse and your secure GoSend locker. This address is similar to having your own PO Box in the States where you can ship any products ordered from American retailers. When you checkout from US retailers, you will use your U.S. address, and your items will be sent to your GoSend Locker. Don't forget to include the unit number! Your unit number allows us to assign each delivered package to the correct GoSend Locker.
