LOL - So you are the the person who sets the price of any given item ??? I bet ebay just cancels the auctions you report, NOT. Any body can sell any item for what ever they want and it's not up to you to try to police the prices.
As far as the high shipping costs ebat really took notice and started charging Final Fee's on postage to correct this way for a seller to make more money but all they did was make more money from all sellers. If you don't like the high postage DON'T BID on an auction, I will always look at postage when I go to enter a bid so I won't pay more than I wish to spend.
