I have a story to share. A sustainability fail. It went like this: we needed to buy new brush heads for our electric toothbrush. We decided to put in a bulk order, reckoning that this would mean that less packaging would be used overall (it would also be kinder on the purse in the long run). Good sustainability logic. Total fail in practice. The parcel arrived, and we opened it to find tens of packets containing just a few brush heads each.
