Do miracles happen?

Got a new email from Dell, this time in French and German. Why one can only guess, but the delivery date has now miraculously changed to tomorrow. Very specifically tomorrow, but less so on time. "Heure de livraison : entre 9h00 et 18h00", which I interprete to be between 9 in the morning and 18 in the evening. Do they really expect people to stay home a whole day waiting for them? Well, I guess unless one of us is home at the particular time they choose to show up, I will have to go to the post office to pick it up. How difficult can it be to plan a delivery route? Ever heard of logistics?
