The website is called wow-advantage
Do not buy this.Obviously everyone should know this is fake. Some people just feel tempted to waste their money on something that can help them. I have found out that if you put download.php after the / like so...
wow-advantage /download.php
It will take you to a screen where it says Your download period has expired.
The reason I am pointing this out is because I have seen someone called Drunes going around WoW telling people about this. DO NOT BUY THIS!!
