I've been reading about the USPS Automated Package Verification system for some years now, but up until this past week I had never experienced any notification of my own. Now all of a sudden I've had two, and the results have been... mixed... though not bad for me (so far).
The first one arrived a week or so back, about a routine padded-envelope shipment that always (always!) weighs 3 ounces. USPS had decided, probably on the basis of weighing two things at once by mistake, that the package weighed 9 ounces and that I owed them another $1.17. I promptly fired off a dispute via the Dispute link on their website, listing the tracking numbers of three prior shipments of the very same thing, and I see this morning that they dropped the charge.
At the same time (this morning), I now have a brand new notification that another of my routine shipments, a 6"x4"x4" box weighing 8 ounces, was somehow overpaid and that its true weight was measured at... one ounce. I cannot imagine how that could happen (helium-filled bubble wrap?), but they have already credited me $1.13 for my "error." No, I am not going to spend time appealing that. I'll consider that credit as payment for having to appeal their first error.
