In case you need to edit the shipping address after you placed the order (e.g. because you noticed a typo), you can do this from the order details page.
Go to Orders and find the order you wish to edit the shipping address for. Then click on the Edit button next to the shipping address.
Important: You can change the shipping address only before your order is dispatched.
Note: You will be able to edit only certain fields of the shipping address, namely the Company name, Address line 1 and Address line 2. If you need to change the postcode, city or country, you will need to cancel the order and place a new one.
