Typically the shipping address on an order can’t be changed once the order has been submitted because the shipping label is created at the time of the order being placed.
If you contact us, we can attempt to change the shipping address, but can’t guarantee that we will be able to do so. Once an order has been processed for shipping, we won’t be able to change the address.
In general, during checkout you can change your delivery address on the shipping page before you pay.
If the order cannot be properly delivered it will be returned to us and we'll reach out to you from there.
