!!!! ATTENTION PLEASE AMERICAN CUSTOMERS !!!! Because of customs duties having to be paid on the first $, parts sent to the US have to be sent by courier service which varies from € 25 to € 35. Please get in touch with me to pay for shipping before any purchase, so I can invoice you for the total amount. Also let me know if you want me to declare a value lower than € 80, if the price above that amount.
These rules are bound to change over and over for no reason.
