> incorrectly packing boxes, not trucks. From Amazon's point of view, they're doing both correctly. Their algorithm apparently optimises for packing completely filled tucks leaving the warehouse first, then optimises for minimal packaging second. If they need a few more boxes of a particular size, to completely fill an outgoing truck, they will split some orders appropriately so that those boxes appear on the conveyor at the right moment. This means that sometimes you receive an SD card in an A4 size box, because that was the only item that was available when they needed an A4 box to fill a truck - and the algorithm decided that the trade-off was worth it.
