I paid extra for 'AM weekday' delivery. Having done this i assumed i would be given notice of when the item was to be delivered. As it turned out the driver called me 5 minutes before he arrived at my property and nobody was in. In addition the item was delivered at around 12.15, so not in the morning. The driver did what i asked and left the item at my house. I would have been extremely dissatisfied if he had not done so. However, this did mean that took the risk of having an expensive item outside the front of my house for 5 hours. I would recommend you call customers the night before a morning delivery and again one hour before arrival. This is my view of best practice.
