I won this chip yesterday : https://www.ebay.com/bfl/viewbids/164840282064?item=164840282064&rt=nc&_trksid=p2047675.l2565

What is weird is that if you look at the history of the bid history, the price goes from $110 to $299.99, that is one cent below my maximum bid. As my maximum bid was $300, the price of the chip reaches it.

It seems a little bit suspect to me that the price goes so high so quickly without any intermediary bids...

Is there a way the seller knows my maximum bid? I have the feeling that there is something wrong with this. What do you think?
