If an item has already been processed for shipping, you will not be able to change the address.Purchase: Shipping Changes
You can change the shipping address on your order through the account settings menu. Once you place an order through one of our stores, we try our best to set your items to ship as soon as we can. This means that often, you are not able to change the shipping information for your order because the vendor has already shipped your item. As a rule of thumb, order shipping can typically be updated on the same day as order date, though it may be possible that your item has already shipped.
To update your shipping address:
1. Log into your account
2. Hover your mouse over your name at the top-right corner of the site
3. Click Purchases from the drop-down menu
4. Click on Details next to the purchase
Again, you will only be able to enter your updated shipping address here if your item has not shipped.
