Is the home letterbox and mail box obsolete?

As emails and internet shopping have become more popular the normal mail service has diminished considerably, whereas the parcel delivery service is booming.

The sensible thing about the Oz-eBox and Jo-eBox is that it is all of the following:

Letterbox If you want mail delivered.
Collection box If you want something collected.
Grocery box If you want groceries delivered.
Parcel box If you want parcels delivered.
Drop box If you want anybody to drop anything off.
Parcel Locker If you occupy a home in a corporate or residential building.
