Where a tracking number is provided for your order, it is emailed to you on dispatch; some shipping methods are not trackable once the parcel reaches the destination country. Delivery times are estimates rather than guarantees, and peak periods or customs checks can extend them. Some shipping methods we use are sent on a delivery-duty-unpaid basis, which means any duties or taxes charged on arrival are payable by the recipient. Import duties, customs fees and taxes may be applied by local authorities in the destination country and are the responsibility of the recipient where applicable by local law.
