Basic Rakeback v. Bonus Question

[ChrisEuph]

If I sign up for a rakeback at an affiliate site, can I still clear the bonuses I read about on the other boards or Bonuswhore.com I am very new and it seems like I may have to enter a promotional code at sign up to get rakeback. Doesn't the bonus also require a different code. Do the codes from the affiliate sites include the bonus?

All help is appreciated, Thanks.
