I think that allowing sellers to revise their opening bid or auction duration is a plus for eBay. There have been many times when I have watched an item I listed sit, sit, sit, never to get bids because it was priced incorrectly. Now, into the 5th day of a 7 day auction that appears to be dead we have the option to decrease the opening (or increase if necessary) without having to relist. Thank you eBay.
