I read the story and honestly don't see that the writer is at fault. Sure, criticize the woman for not knowing better, but that's where her blame stops and Amazon takes the rest.
I'd still argue that it's really better to buy expensive brands at shops licensed by the brand.
I can be pretty sure that I don't get a dud, when I drop 800$ on a Rimowa suitcase in one of their stores. Not so much, when ordering from Amazon.
