Ebay Change In Auction End Policy

Now I understand the concept, If you think something has a particular value you should bid it and stick with it and that should be the end if you don't win, then that is it. But, what about those who bid and then are outbid (like i recently dealt with) in the last 10 seconds. Upon re-evaluating, we as bidders may actually deem it worth more. Shouldn't it be that much like a real auction things do not sell until everyone stops bidding. Perhaps ebay should only kill an item 10 minutes after the last bid that way people can re-evaluate what the item may be worth. After all, this would make sellers happier because they would make more money. And ebay should be happier too. More money for sellers means more money for ebay when they take their cut. As well, bidders will no longer have the bitter taste in their mouth such as I have now for being outbid in the last 10 seconds with no option to rebid.
