PRICES FOR JUST BOXES OR JUST THE GAME MANUALS ONLY

Would be great if you had a price lot page for items being priced that where say just the video game loose with the game case and no MANUAL or say the prices on the game and manual only without a case or loose prices on all manuals only that would be great this way people will know more when they come across the item. Also would be great if you could have a wanted page or a sales page for finding game elements like just the MANUAL or artwork / box.
