I have had bad experiences dealing with overseas shipping with far more expensive items. USPS could not locate the $5k package but said they were looking for it. I finally received the item and the package was thoroughly soaked, like it had been sitting on a oading dock in the rain. Customs had apparently dismantled it to see what this coffee grinder was all about and put it back together poorly and left it out in the rain. It was all the Customs Services that got involved in Germany, USA and god knows where in between..
Anytime something leave the Country of origin you are opening yourself up to the vagaries of every overly officious wingnut in the system.
I used to do business selling custom made items in Europe and the England and Italy and finally gave up because of Customs hassle, and USPS. DHL was the most reliable but also the most expensive. I sent items to tourist locations for them to hand carry items back to Europe just because of USPS and their inefficient system.
