An essential part of the real life bargaining experience is that you're stuck with the attempts you make and, short of finding a new vendor, you can't try again with a clean slate. How do you propose to deal with users who (eg) open multiple incognito windows in Chrome? Or will users need accounts and need to be logged in even to have a go? It seems like users will naturally want to game the system. I felt the experience was cheapened by the fact that the 'bargain' button made it obvious that the starting price was very inflated. That is not always apparent to customers browsing in a store, and perception counts.
