No, it's likely to be different legitimate print runs. Sometimes the same paper is unavailable, sometimes a book moves to a different manufacturing method based on demand (e.g., offset to short run to print-on-demand). The source of Amazon's problem is their third-party marketplace and their practice of "co mingling" third-party stock with their "regular" stock -- this is unlikely to be the case with Barnes & Noble
