Open and save the Auctioneer files in the directory "World of Warcraft," "Interface" and "AddOns."

Login to World of Warcraft. Click the "AddOns" button at the bottom left of the screen. In the AddOns window click "Enable All." Click "Okay." Then enter your server.

Go to the Auction House (AH) and open an auction window with the auctioneer. Make sure all of the check boxes are checked on the left. Click the "scan" button at the bottom of the window. The addon Auctioneer will scan all of the auctions currently on the AH and record their prices.

Click on "Search Auctions" in the auction window. Now set your search parameters. Play around with these to see what results you get. A good starting place would be "min pct less = 50," "max time left = very long," "catagory restriction = trade goods," and "minimum quality = uncommon."

Click "Search" and check the list of items on the right. You want to pay particular attention to any with very high "pct" numbers. This tells you that the item is listed far below its normal selling price.

Mouse over items that interest you. Auctioneer will display a popup window for each item and list its average bid and buyout prices.

Buyout an item that Auctioneer lists with a much higher average Buyout price than it is currently selling for, then relist it for the average Buyout price.
