Is the signup bonus and reload bonus stackable?

My girlfriend is ready to jump into the real miney games. Since I play on Party Poker she wants to play there also. I think that there is going to be a reload bonus tomorrow (Thursday) or maybe it's next Thursday, or the one after that [img]/images/graemlins/confused.gif[/img]

Anyways... there is a 30% singup bonus. Is she able to get both the signup bonus and this month's reload bonus?

Thanks for the help.
