I've had some issues with packages not getting scanned by the postal service. Some have only been scanned at their sorting centers but not at delivery and others haven't been scanned at all. This would not help me should a customer fail to receive a package as I wouldn't even be able to prove to the postal service that I shipped the package!
I usually avoid the Etsy forum like I would avoid the plague but I
ventured in there to ask about sellers' recent experiences with USPS
scanning their packages. A simple question quickly devolved into the usual Etsy forum snarkiness and condescension. What has happened to normal, civil discourse? This wasn't even a controversial topic!
