Clean Sweep Auction Bidding Process

[Stampsfan]

I just bid on some items in the Clean Sweep auction that just completed tonight. I will say I am not a newbie when bidding in many of the fine auction houses out there, but this is the first time I recall experiencing this.

I had an "old guys" hockey game on our schedule tonight, so I threw some bids on as I would not be back before the auction closed. One lot I threw a bid in of about $500 more than the previous bid. I would have put in a "Maximum Bid", but the drop down did not allow me to do so. Therefore I put in a bid.

I come home now, and my bid is about $550 above the next lowest bid. I bid almost $1400 (hoping it would stick), and the previous bid was $835.

I guess I expected my bid to be bumped based on the next lowest bid. I know some will say "You were willing to pay that much", and fair enough. However, this was not my expectation, and I have not experienced this with any other auction house.

Are there other auction houses that operated this way? I have bid in many (REA, LOTG, SCP, Goldin, Mile High, Memory Lane, etc.) and I don't ever recall this happening.

Thoughts?
