I get all of my CDs from http://www.paletweb.com . Unfortunately, many CDs are sold out and not reproduced which means that it requires a bit of luck to get some of them, especially older ones. The thing with paletweb is, it is the only shop I know (aside from jlist) that ships internationally. All the other shops that sell Touhou related merchandise only ship inside of Japan, at least the ones most circles have listed on their websites. That being said, paletweb does one hell of a job and has a great customer support. So basically you have two options: 1) Request the CD on paletweb (you can also send a question to them and ask if they can obtain them somehow. Whether they can or not depends on the circle.) 2) Ask a friend in Japan to order the CDs you want in one of the shops that ship inside of Japan, then have him send it to you.
