Can I change my delivery address after I’ve placed an order?
You can’t change your delivery address for an order you’ve already made. That’s why we advise you to regularly make sure that all your address details are up-to-date. If you change your delivery address in My Account after you’ve made an order, your new address won’t apply until your next order.
