I once complained about rubbish packaging for an Amazon item (loose in a plastic bag and as a result got damaged in the post). The reply I got was that Amazon makes sure all the packaging it uses is suitable for the purpose. Now I suspect the item may have come loose from its original packaging and been put in the bag by the post office, but I have no evidence that was the case and there was no post office sticker to say that had been done. I would have hoped Amazon would have looked into the matter, but all I got was a brush off.
