2 quick things:
1) I have no idea what it sells for on your server. It could be insanely expensive, or it could be dirt cheap. Best thing to do is grab auctioneer, the auction house scanning mod, and run a scan every day for 2 weeks. After that, you should have a good price for your realm and faction.
2) All of what I said aside, Allakhazam has an average price on all servers. Use the search box to the left and enter what you're looking for. Since I'm in a good mood(my sweetie brought me some Tapioca
