>inventory “co-mingling” is a myth invented by fantasist. If that’s true, then any merchant could send in fake items to Amazon Warehouse then request them returned so there will be legitimate items exchanged in. It is true, and it does happen. This is why any wise Amazon seller will use Amazon labeling (an Amazon-generated barcode specific to that item and that seller).
