Well, I signed up for Pokerstars using the ' free' start bonus from Pokerstrategy. I added USD 100 with my credit card to avail of a possible additional bonus. After a few months I found out I'm not that good at poker, so I decided to quit. I had consumed my USD 50 from Pokerstrategy, so I just wanted my USD 100 back. Guess what. I had been playing with my own money, not the USD I got ' for free' from Pokerstrategy. Thanks Pokerstars!
