Delivery costs vary with the service chosen, the item's origin and its destination, and the full amount appears at checkout. FARFETCH's orders and shipping page gives no free-shipping threshold for Saudi orders.
Brands and boutiques are given two business days for order preparation, and buying from several sellers can mean it arrives in separate parcels.
Changed your mind? Cancelling before your shipment has been prepared refunds everything, shipping included. Made-to-order or personalised pieces, however, can only be cancelled within 48 hours of the order.
