Just in case anyone is interested in ordering a Kindle 3 from Amazon.com, it is possible to have it shipped to Hong Kong. The shipping cost table is not very well written on their website but when I order mine (plus a case), it came out to US$26.97. Based on my understanding of the table, I would have expected it to be either only US$14.99 or US$20.98. It is this much because it can only be shipped under the Priority Courier option. Standard or Expedited shipping options are not allowed. So if you plan on ordering a Kindle along with other items like books, don't do it as a bundle unless you really need those other items within 2-4 days. Just do two separate orders instead. I ordered four books and the shipping on them went from over $50 down to something like $23.
Let me know if you have any other questions.
