RedNines rakeback on RakeTheRake

Can somebody please explain this better? Is this actual rakeback or what? It says "The promotion will start on August 1st 2007 and end on September 30th 2007." Does this mean that if I sign up now, I only get this promotion until Sept 30, and after that I get no more rakeback? This page isn't very clear.

Is there a better rakeback affiliate for Rednines?

Thanks
