In an event of an order being too large to use our regular courier services, we withhold the right to request an additional payment to be made before sourcing your parts. This will always be done before your order is ready to ship and you will have the opportunity to reject this order at this time.

Since January 1st 2021 ("Brexit") we have amended the way that we price and ship orders. We charge VAT within the UK at the local rate. Any purchases outside of the UK may receive a local customs charge. We operate and ship under the Delivered At Place (DAP), also called delivered duty unpaid (DDU), terms. This term indicates that the seller only takes responsibility for shipping the product, and requires the customer to pay any import costs, such as VAT, duties, and clearing fees. Please be aware of this when ordering. You will need to consult your local customs regulations to see what the possible customs charges may be as they vary from country to country.
