you simply ask a few friends to bid the price up thats shill bidding theres also tittle scaming as they call it.
me and tracie used to sell alot on ebay we even reached power seller status but in the end gave it up with all the scammers and hassle with paypal.
the final straw was when a guy bought one item and then asked me to include a second item that had ended being a considerate seller i did he then claimed i had not sent the second item and paypal just refunded his money leaving me well out of pocket.
its all geared towards the buyer they can leave negative feedback and the seller can not how fair is that ?
