After setting the resale search criteria accordingly you can go ahead and click "search" and now all the items that could bring you the minimum profit set as a criteria or more will be listed. Now is the time you realize that auctioneer is just a tool that relies on hard data and you will have to start using your head and experience. You have to go through the list of items and look for items that you know wont sell and are listed just because of the numbers. For example very old and useless materials and junk that some people list to trick auctioneer etc.

What I like to do is go through the whole list of items and when I see an item that i don't want to buy, I ignore it by selecting it from the list and hitting "ignore" button below the search results. Once you've handpicked all the garbage out you can go and purchase all the items from the list if your budget allows. If it doesn't, simply handpick items with low Pct. you know will sell. Soon enough you will have enough gold to buy the entire list!

To purchase all the items at once hold down CTRL, ALT, SHIFT and the "purchase" button should turn into "Purchase All" then just click it and start approving the buyouts.
