I'm a bit perplexed. I did not know that Noir was sought after these days? Heck, I have a boxed Noir as well. I've actually been donating some mint boxed games to Goodwill lately, as it seems the market is so soft. Maybe I'm making a huge mistake, yet I check this one website which tracks average values of a lot of games in both boxed and non-boxed versions plus sealed and not. Seems like so many games have no value anymore.
As Gelert mentions, seems like this ebay seller is doing a wonderful job of maximizing interest in his game auctions. That likely has a lot to do with it. Some sellers just do a great job of presenting their auction, plus they have a rep for backing up all purchasing with support and help to get it running. I guess I never did a good job of any of that.
