There was one on Ebay a couple of weeks ago. After someone posted about it here,it went for $4000...
Well, it was more like $2700, which is also a lot of money of course . Especially since the bag didn't appear to be in excellent condition, as told by the lucky winner in this thread: http://forum.purseblog.com/chanel/found-mary-kate-ashley-olsen-vintage-chanel-hobo-156371-10.html , posting #145.
