Perhaps your perspective is off. If you ship anything eith a tracking number, can can view when it was delivered.
Confirmation of delivery is asking the shipper to take additional steps, most of the time getting a signature, which incurs additional cost to them (how mnay times have you not been home to sign for a "signature required " package, forcing the delivery company to make multiple delivery attempts?) I personally hate packages that are signature require and hope those are only shipped FedEx because I can more easily go to the FedEx store after redirecting my package.
All the God's, all the Heavens, all the Hells are within you.
