Before we left the European Union, the price you saw at checkout was the price you paid with no tariffs. Our departure has brought some changes. The UK now charges duties on some goods & packages arriving from Europe. The amount charged depends on the total value & comprises import VAT & duty.
up to £39-should be free of tariffs
£39-£135- just import VAT
Over £135 will have import VAT & duty + handling fee.
Unfortunately, these costs are only payable once the goods arrive, so are not part of the checkout price. For further information visit: https://www.gov.uk/guidance/tariffs-on-goods-imported-into-the-uk
