ReloaD1010 no offense...but learn to use auctioneer properly.
Notice the: "Market Price: Not Available". Want to know why? BECAUSE IT'S NOT IN YOUR AUCTIONEER DATABASE. Those "Sell Prices" is what the vendor would buy the item for. You don't sell them to vendors, you sell them to the Auction House.
*knock knock, anybody home in there?*
Observe:
[NOTE:] Sell to Vendor price = 5g 41s 23c (Which is what your screenshot highlights)
[NOTE2:] My Market Price says "seen 29" - your's said "not available" meaning I'v seen this item on the AH 29 times, you haven't seen you item at all, therefore you have no price that you should sell it at.
[NOTE3:] When you don't have a price to sell at, then it will not display anything where as mine has the whole "SimpleAuction 158g 74s 16c bid/198g 42s 71c buyout" and "Undercut..." etc going on whereas yours doesn't.
