Question about CDpoker

I recieved an email today and I was wondering what's the catch. The way I read this, all I have to do is deposit at CDpoker and email the bonus code and within two days, they'll add $50 to my account? Sounds like there are terms and conditions I don't know about. Anybody else know any other information? Here's a cpoiy of that email:

Dear Timothy,

Flop your First deposit bonus + $50 extra

All you need to do is make a first deposit, and you will instantly see your
first deposit bonus in your bonus balance.

Then send an email to (deleted email address) with the bonus code: (deleted bonus code) and she will
credit you with an extra $50 no questions asked.

This offer is too good to leave open ended, so you have 48 hours to make the
deposit, and receive an extra $50 in your bonus balance.

See the Action at CDPoker!

*Please allow up to 48 hours after sending the email, for the extra $50 bonus to
be credited.

The catch is you'll have to clear bonus requirements to withdraw money (any money, not just the $50 you deposited) and these are very punitive on the ipoker sites (CD, Noble, Titan etc). I'd do it though - i'm a CDpoker fan, certainly over Titan and Noble. If you make it your "home" site, you'll clear the bonus eventually.

I'm still waiting on bonus from Titan and CD. They send me an e-mail your almost their! What mine was I play more tourneys than the ring games and that's why I haven't got my bonus yet. They didn't tell me that when I deposited, some of those ring games are with a bunch of idiots(well the ones I got in on). So that's why I haven't got my bonus yet. Think it "sucks".
