whats a "shill bid"? I'm an idiot!
Where the seller, or a seller's buddy bids up the price in order to create a higher selling price. It does that, but also if they have more to sell, it also makes the item appear to be selling at a much higher cost for later sales. Of course, if the shill bid wins they just approach the previous highest bidder and offer to sell it to them.
To me, it is WAY too much work. If your shill bid wins you would have to pay all of the fees, and never really sell your item.
It is what it is I guess.
