Was the item small enough to fit into a small PO Box? Or would it have been 'carded' for pickup at the PO.

I ask because I had a 'trackable' large envelope sent to my small PO Box.
No card was left in the PO box for pickup when it arrived. The tracking showed 'in transit'.

I ended up re-purchasing my item (thinking it was lost) & Aus Post compensated me the missing first item.
When the new item eventually arrived & was 'carded' for pick up - guess what was waiting as well - yep - the first 'uncarded' purchase!!

The PO staff hadn't carded or scanned the first item when it arrived.
