The delivery address was not up to date and now a purchase has already been made. What to do now?

Do not worry! We'll get it right :)

Change the shipping address in My Orders:

If you notice after placing the order that the address is incorrect, open the Orders section and change the shipping address. This will work until the seller has downloaded the shipping label, or started shipping. If you can't find the option anymore, contact your seller via the message button. 

The package has already been shipped?
