Deleting "canceled" items

When you encounter, in the Item List, an item (carrying an N barcode) that has a status of "cancelled", alongside the legitimate, live item, can you delete these? The answer is: yes. Such a status arises when the original supplier couldn't supply the title, and it was ordered from another source. So, when you run across a "cancelled" item, feel free to delete it, thereby tidying up that Item List.
