WTB Massive Jawbones

Alright i've had it. I've tried to farm for these with henchies, I have shouted for a long time in LA/AO/Augury/DF and still no one has these collectibles...

Well, i already got a hold of 2 i need 3 more.

Please name your price, I need them ASAP

Just to make it clear, i need Massive Jawbones. They are dropped by Sand Giant, for one...

Thanks!
