They say no guarantees and all sales are as is. I get the impression this is a dealer selling his own material and guaranteeing himself a minimum 18% profit. He reserves the right to know your maximum bids ahead of time so I doubt he will let a lot close at a loss. I find it interesting that they say they will not accept credit card charge backs. I can't help but wonder how they plan on getting around them? Automatically charging the card again? They try that a time or two and they will find that the card company will simply stop accepting any charges from them.
