I have been collecting the Xbox 360 Kiosk discs for about 6 months now. I have been able to procure most of the discs from 5.5 to current 6.4. I know the earliest discs are extremely difficult to track down. In my experience they are all hard to find. I am hoping there are a few of you that have some to trade or sell. I am looking for anything below 5.5 to build my collection. I have several doubles to trade and/or sell, so please contact me if you have an interest in trading, buying or selling.
