I think I heard a report that around 30% of deliveries to London offices are personal stuff from Amazon and some places are banning it because of the load on their in house posties. The desk next to mine gets a lot of stuff from them at least one a week – fun seeing what he has ordered.
A few years ago on a factory inspection in Korea I noted they were producing and testing our product with about 11 people on the line, but it took another 9 off the side to keep up folding the flat cardboard into a 3D box. Our boxes are custom exact fit with minimum wasted space but also designed to pack efficiently onto the pallet. Custom box design is a big and sophisticated business and can be a significant part of the product cost.
