Empire poker question

I want to deposit in empire and was wondering if I need a bonus code to get the initial 20% sign up bonus. I signed up with a rakeback deal and got the bonus code, but do they give the 20% bonus no matter what other bonus codes you enter or do you even have to enter one to get it?

Thanks

If you used the signup code your affiliate gave you, you don't need to use a bonus code. Your sign up code will give you the 20% bonus. DO NOT USE any code when you first deposit, if you do it might invalidate your sign up code and you won't be able to get rackback.
