If you want to update the shipping address on an order you have already placed, we need to process that request for you.
Please contact us with your order number and your new address so that we can update your order as soon as possible. We will only be able to update your address if your package has not shipped yet.
If you want to update your address because you know you're going to place an order in the near future, you can update the address saved on your account yourself. This method is only for future orders though, it won't affect the shipping address on orders already placed.
You can get there by adding /account/address to the end of the URL of the site you're purchasing on.

Once you've reached the address page, simply input the correct mailing address and click "Submit."
