i do not , im sorry <| sep |>' And what is the significance of the elongated lip ? '' It had to be that way for very personal reasons ! !!!'<| sep |> Stick to ebay . Let ' s take a hypothetical penny auction site . How it works is you purchase bids . Say , $ 0 . 50 per bid . You can then use those bids on any item being auctioned on the site . Each time someone bids , it raises the price by some amount again , say , $ 0 . 10 and extends the auction deadline . When the auction ends , the last bidder pays the final price . So as a third party observer , you see that a $ 400 iPad sold for $ 100 . Amazing ! How can they do that ! Well , $ 100 is equivalent to 1 , 000 bids . Each bid cost $ 0 . 50 , so that ' s $ 500 they make just in bids alone . Add to that the final price of $ 600 , then they make $ 600 on a $ 400 product , for a profit of $ 200 . What ' s the final cost to the winner ? Well , that depends on how often they bid . The site Quibids says on a $ 400 value item has an average of 25 bidders . So that means each in our above example those 25 bidders had an average of 40 bids , or $ 20 worth of bids . So the high bidder actually ended up sinking $ 120 into the product . Not bad , though Quibids also says that the winning bidder on such a product actually averages around 66 bids . But , the thing to take away is that all of the other bidders are just out $ 20 . They paid for those bids and got nothing in return . Sites like Quibids play down this part and emphasize the final price . A real auction is simple the person willing to pay the most gets the item . It ' s not a competition or a game , it ' s just a mechanism for getting the product to the person that wants it the most And can back that desire with money . Penny auctions are a game , a competition that you must pay to play and occasionally you get prizes . In its purest form , it is the Dollar Auction which , when played optimally , ends up being an infinite game where people just keep bidding to minimize losses and the best move is not to play . The TLDR is , treat it as a form of gambling , not a way to get used items for cheap . FOr that , stick to eBay .
