Amazon is no longer capable of packing books. They just toss them in a box with some of that crumpled paper and by the time it gets to you all the corners are smashed in from sloshing around in shipping.
You could complain about the packaging, but it’s not quite as easy as using their app to take a photo. I’ll note last time I ordered a book from Amazon.com for international shipping to Canada, it arrived in the pressure-tight cardboard packaging I expected.
I ordered an audio CD set from Amazon.jp and it arrived faster than it would by US ground and the packaging was flawless, with Apple-esque plastic attached to the easy-open cardboard to keep every corner perfectly sharp.
So... it varies by region?
Or I’ve gotten lucky, n=1 ;-)
(Aside: that’s the annoying part about Amazon, 9 times out of 10 it’s exactly what you expected but then there’s that one time, maybe you buy something you wouldn’t normally, or the box is mostly empty, or the item’s serial number is invalid, and... you really don’t know what you’re going to get sometimes. And Amazon doesn’t make it easy to report it, it’s simply not something they visibly care about...)
