Two boxes
I often wonder if online companies have some sort of quota for the number of cardboard boxes that they have to use within a month. That would go a long way to explaining why so many of these delivery examples involve doubling up on boxes.
It looks like all this person ordered was a tiny battery in a bag, but it came inside not one cardboard box, but two. Oh, and with some scrunched up paper as well, just to add to the whole experience.
