From what I have seen people do arrange drop points once they get to know the delivery guy. If the guy leaves to another location it has to be arranged again with the new guy.

By having a standard UPS/.. could be notified that you have a "A1" container available. Any parcel that fits in that container can be delivered without arranging a meeting time. It could be done today in rural households but in cities, room would need to be made for these new containers.
