Any market for empty game shell cases?

[Outlaw]

Hi everyone, I'm new here. I have a handful of old collector's edition stuff I'll be listing in the near future. Before I do though, I was wondering if there's any market for game cases/manuals sans game.

You lot seem to be more hardcore collector's dealing primarily in steelbook/collector's editions but I remember on some of the old game forums I'd frequent people would occasionally be looking for simple cases because they purchased the game from gamefly or gamestop and didn't have the case/manual to go along.

Are empty cases/manuals something I should bother listing?
