What I found most amazing about the eBay auction of Web 2.0 startup kiko.com was the runup to the sale price of $258,100.00 during final hour of the auction, as seen in the bid history:
What do you see in this bid history? There were at least five serious buyers who pushed up the price by bidding and counter-bidding. In fact, someone with eBay account name of wswire was beaten by powerjoe1998 in the final minute.
May be this is not so amazing in eBay auctions, especially for unusual items!
