Not enough to make it worth it. Try trading in maybe?
Not much.
as with all systems you'll get a little more if it looks good and your able to describe what works well and what might have some issues. you wont ever get much so its better to use it for store credits or for games to use on your new system, it depends. however. they do have a facebook page that you can ask them from and they'll give you a proper amount on what its worth to them.
