Bonus whoring on Empire via IGMPAY

[aesic]

First time bonus whoring.

I plan on depositing $500 into Empire to get the 20% bonus. I have read that you can also get an additional 20% bonus if you sign up for IGMPAY and use the bonus code "IGMPAY". Do I also need to enter a bonus code for the the Empire bonus, or will that be automatically awarded? Also, is this information that I've gathered correct?
