OP, that's a really good question,
you should prob pm Kiera, David Sklansky or Mason Malmuth for a more detailed answer (I recommend Sklansky...) but until they get back to you, I've found this on the 2+2 bonus program
PartyPoker page, it might be useful:
'4.
Free books are sent once you have signed up, made your first deposit, and earned 5 Party Points, unless the deposit is made via MONEYBOOKERS, WebMoney or PaySafe Card i
n which case you need to earn 30 party points.
Party Points are a like frequent flier miles and are earned
based upon the number of hands you play and the limits you play at. See the site for specifics. The points may be exchanged for merchandise and other rewards.
The five free books do not require the redemption of Party Points but you must have earned them.
We receive information about your qualification from the site approximately twice a month so please be patient.'
You will have no problem clearing either five or thirty points in a matter of hours, regardless of stakes played, if you multitable a little. If you're playing one table....wtf
, but anyway, it'll take days rather than weeks at low limits.
Hope this helps
