Shipping Notice for USA Customers UPDATED 9th Nov., 2025
Due to recent updates in the tariff policy by the U.S. government, shipments from the UK to the USA may incur duties or import taxes, ranging from 20% to 40% of the total value. As a result, we will mark most items at 50% off of the original order value. In order to minimize the import duty charges, we will take steps that we hope will not cause any issues for you.
