In my neighborhood, we are noticing a new phenomenon. I can't quite figure it out, and thought perhaps the PP brain trust could shed some light on this.
I and many of my neighbors apparently have signed up for Amazon Prime, which features free shipping, and generally 7 day a week delivery in a pretty quick manner, like 2 days.
It seems they are using USPS for some, but not all of this business, and the way these generally small packages are delivered is much more sloppy than the normal mail delivery.
I have found boxes on my lawn, on my sidewalk with one dented corner as if thrown from the truck, etc.
The latest is many folks here are saying they did not get a package that Amazon shows as delivered. I know there are a lot of things that could be going on here, but I am guessing that mail carriers are PO'd about this work for some reason. Any body have any ideas? Anyone else seeing this in their area?
