This is the most apt, insightful description I've seen so far of what is evidently a growing problem for Amazon: more and more retail consumers no longer trust the merchandise being sold by Amazon.
I write this as a longtime Amazon Prime member who, recently, for the first time ever, decided to buy a relatively inexpensive product (filters for a fairly expensive espresso machine) from a bricks-and-mortar retailer instead of Amazon, because I could not trust that the products listed for sale on Amazon were genuine (as opposed to knock-offs) or even the right kind (made with the right kind of silicon).
