For example:
Fuji S5000 Digital Camera
Ebay should say minimum selling price is $329. If somebody tries to sell lower than that, the site would give them an error. Hopefully this will not kill the market and let people try selling it for $5 profit. I know the starting fees would be higher so if they want to start the bidding at .99, eBay should automatically put a reserve price on it for $329.
Just my two cents
