Well through out all my pet battles and bags I'v collected 3 Flawless Battle-Stones and as you know are not soulbound and so am going to put them up in the AH, but I'v never seen any in my servers AH so dont know really what to base the price on one off these babies, so just putting it out there, how much would you sell it or pay gold for???
They are going for around 9k-10k on my server (Hellscream US) and from what I have been seeing posted around here 10k is about the norm.
