Warning to U.K buyers. Please be aware we have been informed that Parcel Force has been charging a " handling fee" as well as making you come pick them up on USPS packages coming into your country and in some cases between the customs fees and this charge it can be 1/2 or more of the item cost. You will have the same issue with any other seller but we wanted to make sure you were aware of this prior to purchase.

International buyers are responsible for all Customs fees and any additional fees that their country may add to incoming packages as those are something we have no control over.

Kits that have been opened cannot be returned for credit as we take great lengths to list all of the applicable model numbers in the listing to ensure you get the correct kit to begin with.  Returns must be in the original shipping box and received by us undamaged to qualify for a refund.
