Just an idea. I have noticed that on an order placed for an item that shows out of stock but turns out to have been discontinued after the order is placed there isn't a notification to let the person who ordered know that it has occurred. Unless they are on top of checking the parts on the site directly the order just sits there and remains in a "not in stock" status. I can see where this can be very frustrating for some who don't look into the reason for things not being in stock and just wait, checking the order and continue to see the same result. idk if there is anything that can be done to correct it other than the person checking to follow up on it like I do. It may be something that CC can look into to prevent any disgruntled customers in that aspect.
