Tracking USPS Signature Delivery mail- WTF???

But it's marketed that you can track your letter/item during and to its destination. when if I understand your sharing here we can only track an APC that contained our letter at least at one time while our letter maybe somewhere else taking its own route to the destination where its retracked on its final delivery?

That constitutes smoke and mirrors in my book, maybe bait and switch?
No not really, there is no requirement to provide tracking and the fine print clearly states that tracking is only an estimate.
