i don't know how it works but i heard they are legit. i think they buy tourney money from people that normally can only be used to play in tournies rather than withdrawn as cash. i never read it so don't really know. the link is okay.
dont use em.....they are a rip off......there are poker forums that you can go to that have places where players will buy/sell tournament money and you will get a lot more than cashmanbrian will give you.
Im pretty sure they just buy the tournament $ or whatever you win in satellites or however you get it for a discounted price. Like Tease said, you can def. do better somewhere else or finding someone to buy it off you from a forum.
