Netflix now allows users to buy used discs from their library. They include a case and the original cover. Prices (of the ones I’ve seen so far) range from $5.99 to $9.99, which isn’t bad at all to add a movie you really like to your collection. Of course, the current selection (for purchase) is slim and there doesn’t appear to be any television series discs. I would think the next logical option would be to allow the user to simply keep a movie they’re rented (by adding the charge on their monthly fee) and have Netflix just send on the next off of their queue. Of course, this all assumes Netflix isn’t just selling off the back catalog to switch to a download service. (Sorry, no link. If you’re a Netflix user, just look for the new Buy DVD’s tab.)
