I am planning on purchasing a Birkin from France.. the seller said he would ship it via fedex. I am very concerned about customs. Has anyone bought a Birkin from over seas, who had to pay the actual amount of duty fee? How much should I be expected to pay. The seller said, he would mark it as a gift under $500 but I've read that customs are now cracking down on that and I don't want to risk having my bag stuck on customs. Any advice will be appreciated.
