We're pretty quick at getting your order out the door, so once your order has been placed, our customer support team is unable to make any changes to your billing/delivery address.
If you've selected our Express Shipping service via DHL, an address change is possible. DHL offer an online service called ODD (On Delivery Demand) which you can use to make the delivery more convenient for you. Here's the link for the ODD service:
You'd simply follow the link, enter your tracking details then hit the 'change address' section and the rest will be easy to follow.
Your order will need to be shipped before the ODD service is available, so please wait for your shipping confirmation to come through.
