The recently built Amazon shipping center NW of Grand Rapids looks to be at least as large as the decades-old UPS shipping center on the south end. I see Amazon trucks all the time, and not just because they're in my driveway here in The Boonies.
I saw two UPS trucks one day last week, and while driving by the second one I got thinking, when was the last time I saw even one?
I get parcels through USPS (books mostly, also little dongles and other doodads) much more often. When I get med supplies I never see who does it, but they always leave it right by the back door and I appreciate it.
Back in the ‘90s I worked part time at our local UPS hub loading aircraft shipping containers, also referred to as “cans” on the overnight shift, as well as my full-time day job. I worked there a little over a year. Christmas was brutal. I swore I would be out of there before the next Christmas, and I was. I was in my 40s at the time. The part time money was good, with full benefits (Teamsters, after all).But it got to be too much.
Of all the carriers, UPS is my preferred given the driver has been the same for many years at time. I got to know them by name, and they had my cell # in case of any shipping issues. Fedex and USPS to a much lesser extent, and I’ve never noticed the same Amazon driver more than once. And as mentioned upthread, some Amazon deliveries are made with the driver’s personal car. Amazon’s warehousing also makes 4-hour overnight deliveries a possibility.
