Probably have cancelled items; either due to a) over ordering and not getting enough pre orders for the product, b) ordering only for me and having to cancel due to finances, or c) (and what has happened too many times) is not being allocated any product to my order and having to cancel and order from someplace else.

Take Japanese Grimlock and Ratbat. Originally had 10 on order, changed to 8 of each. Allocated 0. Cancelled and ordered from Robot Kingdom.
