Nothing left over for a horde pally. I am not sure if multiple pallies can do it at the same time on set of stuff. I don't think so. If I remember correctly you buy all the crap and then give it to some dude who takes it and gives you something in return.

Horde side is like 10x easier then ally. so if you are horde you can try it out on one set then go back if it didn't work.
