Boku better not go broke. I tried selling 2 million playchips today, and the best offer I got was $2 per million at a reputable site.
Oh yeah, and PS has no $ freerolls to speak of. There's the Hubbles, but those are satellites to a Saturday tourney. The Daily Eighty Grand is the only one I can see, and only 27 places pay. Good luck with that.
The fastest/safest way to make money with $5 is .20 5CD.
