Speaking of Amazon, I recently ordered a dozen books (graphic novel volumes - don't judge) and when I received the box I opened it to see that they were just placed inside of it. There was no padding, no bubblewrap, nothing. Just a bunch of books placed in a large box. Needless to say, one book had pretty severe cover damage, one was moderate, and the others showed pretty mild signs of the shipping process.
I contacted them and got things sorted out, but that was a first. The seller/shipper was Amazon itself, not a marketplace user or anything like that.
