I'd almost swear Amazon does this maliciously. One item per box.

Unless you have a small delicate item and a large heavy item, in which case they put them in the same box with no void fill.

Usually doesn't obviously damage the small delicate item, but I have to wonder if it's subtly damaged, etc, for the experience.
