I notice that the Apple iPad case seems to be in short supply in the US. I don't want anything to delay my iPad UK delivery on the 28th of May. I have noticed that my order status makes a note that my order will be shipped when all items are available. If the case is not available, do you think my order will be held back? If I cancel this particular line of my order, will my whole order be re-evaluated and given a new shipping date? (aaaargh 7th of June!!!!) Appreciate your thoughts and experiences please.
