The address you are given to send the item to will be the authentication centre and not the buyer's address.
You may have an issue with authentication because the final picture in your listing is NOT of the bag you are selling, it is a different bag.
It is really important that the pictures you use actually show what you are selling.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
