Well.. i know that some country are strict ...'cos i come from one such country (Myanmar)... and in my home country, there is no credit system too.. but I didn't know that you can't get any CDs in Iran. really sorry to hear that..

As American XS code is only used once (I think so , someone pls confirm me on this), you may not be able to do that.... I think there are 2 ways you can do..

one is get the ripped version (mp3) of the songs from American XS ..or Another is asked somebody in other countries (preferrably in US) to buy the CD for you and tell you the code and you can arrange the payments later by bank draft or money order or whatever is available...

Hope this help
