the auction with the lowest price at any point in time is the one that is visible, if there are multiple auctions for the same price and they are all the lowest then the auction that has been up the longest, or is closest to ending is the one that you see. Therefore you need to create your auctions so that they end when the most people are online. Make many small auctions spread out over that timeframe and they will sell. Hint: start them Thursday morning so they end Friday night.
