actually one of the rakeback providers is saying it will affect rakeback this time around. I'm skeptical about it because it never has in the past. So I guess just have to wait and see.
i was under the impression that it does effect rakeback after reading a similar post last time the promo was around. one of the members here broke it down very well and if my memory serves me correctly they did take a small amount of money off of me after completing the promo. promo is still worth doing regardless if it effects rakeback though.
