Try that link, they're selling it for 331.60$ and it's used with "minor marks".....

They're essentially one of those liquidators (like demo models at bestbuy/extra inventory), you can see their main site:
dealtree.com

They're genuine and you can pay with Google checkout so even better.

Their policy is to submit the items to eBay if they haven't been purchased for some time.

$340 (when you include shipping) for a used N810? Doesn't strike me as a deal, when a new one is $352 at Amazon.
