Just to show that we do get the occasional one that does indeed have intermediate scans here is an example from earlier in the year.

This particular order was received on a Friday night but we did not get to pack and send it until Monday afternoon, the next available postage time for us.

This one did have an intermediate scan event the day prior to delivery. But that event was five days + after the buyer had paid.

Had we droppped this one into a red street box the next (first in such case) scan event was outside our handling time so we would be open to a late delivery defect on this one because of that fact and that delivery happened a day after the ebay EDD.

But because we had the lodgement scan on Monday afternoon at 2:30pm inside our 3-day handling time then we were protected from the late delivery defect. 

In this example, if it had been lost by AP then the only scan event would likely have been our lodgement scan proving we did indeed send it within our handling time. Covered against INR under ebay MBG.

So whilst I understand that not everyone can get to a PO to lodge over the counter it's actually very important to do so.
