Now that you know what to buy and how much you want to spend, you need a way to do that automatically .... and this is where Auctioneer becomes really useful.
•Run another full scan by clicking the double arrow at the top of the AH panel
•Go to the Search tab and Searchers > Snatch

The Snatch function of auctioneer lets you build a shopping list of all the items you want to buy and the maximum price you want to spend on them. To add an item just :
•Drag and drop it in the frame
•Set a price for this item, check "Allow bids" if you want to buy stuff without buyout (Note: I don't do that) and "Allow buyouts" if you just want instant items. (That's the option I use)
•Push "Search" at the bottom left of the panel

Auctioneer will automatically list all the items available at this price at the AH, you can just select one and click purchase or just Ctrl + Alt + Shift click Purchase to buy all the results (and this is what you will do most of the time if you have a decent Snatch list)

It shouldn't take more than a minute or two (scan included) to empty the AH of all the cheap Cobalt / Leather / Eternal Earths etc ...
