Yes there are different offers all over the internet. There are the basic singup bonuses that Party offers. Other sites have deals with Party and offer different first time signup bonuses as well.

I don't know where or what kind are out there because I signed up for Party a long time ago.

I do know that the the bonus IGMPAY is really nice and easy. The first time you signup for IGMPAY with Party and deposit with it you get a bonus of 20% up to $100 I believe. I did that one a long time ago and it's really easy and as far as I know it works for everyone.
