Some orders may be sent in separate packages. Please be aware that we cannot deliver to PO boxes or APO addresses. If you have questions about your shipment, if your order has not arrived within the estimated delivery time, or if you believe your order is being returned to sender, please contact THU Store support.

Shipping costs

To estimate shipping costs, please add items to your shopping cart. The final shipping cost is generally calculated by the quantity of items, weight of the items and the shipping address. The final shipping and handling cost can be calculated from the Shopping Cart.

Orders shipped internationally may have customs fees, duties, or taxes applied to them. We are not able to estimate those costs and are not responsible for any fees collected by customs. To find out more information about these fees, please contact your local customs agency.

International Shipments

All recipients outside of the EU, are responsible for any local import duties, customs and brokerage fees, or taxes that may be charged. Usually these charges are paid for by the carrier on import of the shipment and then are invoiced to the recipient on or after delivery of the shipment.

Standard time in transit does not include Customs clearance.

Multiple Shipments

When you place an order of several items we will do make our best to package the items together. You may have ordered items that could not be packaged together (i.e. Apparel and Sketchbooks), and therefore had to be shipped separately. If all shipments have not arrived within the estimated delivery times, please contact THU Store support.

Shipping Damage

Should your shipment arrive at your delivery address damaged, please do not accept the shipment, or have the courier confirm the damage. Since courier services will not accept damage complaints that are filed at a later date, we will not be able to offer compensation or exchange in such cases.
