Be wary of dealers that raise the value of the item they have available for bidding by bidding on their product under fictitious accounts. If you find a person attempting to outbid you but only on minor increments of your bid every time, most likely prospective buyer can be a shill. If you notice a good deal on social media websites just like Twitter or Facebook, do not quickly click the shortened Url they give you.  Preferably instead, check out the particulars all by yourself starting with verifying the merchant's actual internet site.
