Platinumstorm, read my reply to Anty above. You losing profit on an item is not the fault of MW or AH or price listing, it's the fact that there's no way right now to remove an item from circulation once someone purchased it. The market is oversaturated with a particular item and the price goes down naturally, not because it was influenced by the trading system. Compare low level items with mid and high level items: I bought an iron chain mail shirt over a bronze one because it was cheaper (because there were 4x the iron chain mail shirts available compared to bronze ones).
