When I buy stuff from the US they usually ship it via USPS First class international, it is both quick and cheap. Why do you have so much hassle with the customs? The forms is as far as I know quite easy to fill. Sure, the post here in Sweden isn´t so helpful either. If I ship international, I have to check the rules before I get there
. But that is the name of the game, I would never rule out international shipping on my own auctions.
Regarding the fees and taxes, I don´t complain. I know when I start bidding or buy things that the total price will be added with about 30% to cover that.
I know that it is difficult to mark shipment as "gift" but "sample of no value", thats a different story.
