"Wierd experience. The website phone number voice mailbox is full and not accepting messages. There is no return address. Despite the fact that they claim to have a 30 day refund period I can find no mechanism through which this would be effected. The e-mail invoice sent was blank. I do not have a good feeling that this organization is well run or above board. Unfortunately, I needed a single disc XP/SP2 rather than 2 disc to load on a Mac and want to return but may be stuck $77 in the hole. The product appears to be what it is supposed to be but will not work with "boot camp" unless it is a single disc installation."
