Getting a friend started....best % return on Party first deposit bonus

[Card08]

Im looking to help my friend get started on Party Poker. I don't plan on benefitting on this so I don't want to impede his $ by doing refer-a-friend. I think that Ive seen 30% up to 150$ codes before, but I may be mistaken. I plan to start him off at the "beginner" tables where he can learn a few things and clear his bonus fairly easily. If all goes well, I will later help him get *unmentionable* at another skin. Please let me know of any good codes that are still working.
