Shipping to the US 16€ with tracking
_________________ Prices are in € = Euro. If not specified otherwise add 6% to total or pay as "friends and family" on paypal. Bank transfer if possible is also fine. If you want to pay in USD I can recalculate the price and it's fine as long as I also receive it in USD (on paypal).
Shipping cost if not stated otherwise is usually calculated as "First-Class Package International Service" with tracking to the US (and most other countries outside EU). I can also send it insured as registered mail (usually cost a little more) or EMS "Priority Mail Express International" (costly). Small parts can be shipped as priority "letter" mail without tracking in padded envelope from 4.50€ (on buyers risk).
Shipping within EU cost a little more (registed mail usually best option) if not sent as priority 'letter mail". Ask for options.
