The problem was that a tiny plastic gear inside the machine stripped and it stopped working. I contacted the manufacturer but they said they do not sell spare parts and I should just buy a new unit. This felt like a huge waste of resources and money for a five…

We have all been there: ordering a small USB drive and receiving a shoe-sized box filled with plastic air pillows (mostly styrofoam). It is an engineering failure and an annoyance. To transform a conventional online shop into a green pioneer, we need to overhaul the unboxing experience. Here is a 5-step roadmap to stop shipping…
