Like needaGF said you cant trade it into cash directly, they offer several tournaments that you can enter with your points though. You definitely get the most value out of the $7500 turbo qualifiers for 25 pts. It's true there's a lot of donks but if your game is good it's not too hard to finish top 15 and then you get a ticket to the $7500 freeroll which usually costs 1000 points to buy into. You're basically multiplying your points by 40 and thus as long as you're winning more than one tournament for every 40 entries it's worth it, and those are pretty good
odds. Also, once you get into the $7500 free roll there aren't many donks so if you're not a bad player more than likely you're going to cash. Of course, if you want to get quick cash back, exchanging 550 points for the $5+.50 tickets is the max value you're going to get as kahntrutahn said. Hope this helps.
