Yes you can receive sub-affiliate revenue from 888.com But again I would urge you to focus your efforts on recruiting players, as finding quality subs is much more of a challenge than it seems.
With 888 being a sponsor here, I too can help you with any specific needs. If you're not an 888 affiliate, you should sign up through PAW and take advantage of the
exclusive U.K. Open Freeroll. Furthermore it is a great brand to add to the portfolio of products you promote.
