To make this work, you have to have massive ammounts of the stuff you want to sell. Me, i used malachite,shadowgems, greater magic essence. I bought around 200 of each and would put them on ah for 95 s each (i would be the only one on there because i would buy out all the others)
After you do that, log off, start a new charactor, get him to a city ,and start asking in trade
WTB XXXXX (whatever you chose) 3g each or 26g a stack And say you dont want to use the AH if anyone trys to tell you its on there.
Some people who will catch on will buy out all of your auctions to go to you to sell, when they do log off, delete the charactor, rinse and repeat.
