You make very good points but I got the impression that Shopping Express may work a little differently. It seems like Google might actually call the store and have the store employees prepare the order, or at least confirm that some items are in stock. One clue was an extremely quick turn around time for out of stock items: my order would be canceled less than an hour after being placed and hours before the intended delivery time for being out of stock. Of course, this doesn't rule out the possibility that the shopper happened to be at my Target at the time and was just buying every item for the day. That being said, you do bring up good points and that may well be the reason.
