CDJapan has a huge number of items that you can't get easily in the United States, and they still manage to have solid prices and consistently deliver sooner than I expect. It's my go to site for all things importing. If you are looking for a soundtrack CD or other piece of JP media that isn't frequently shipped to the US, there is a very good chance they will have what you need. My most recent order was a pair of Xenoblade Soundtracks, which were delivered a day before the release date and just two days after shipment with great packaging. I really can't recommend these guys enough!
