Just a personal anecdote: I've been using Amazon less and less. Most of the goods I buy from them are things that I would otherwise get from a supermarket. Bulk goods mostly, and almost entirely things I'd otherwise get at my local supermarket or Walgreens.

My other purchases are from shopify sites. I trust that what I'm buying is what is advertised far more than I do with Amazon. The influx of crummy knock-off products, poorly made junk, and a lack of quality around product listings on Amazon has completely driven me away from them for things like clothing, shoes, fitness products (equipment, supplements), and anything else that I wouldn't see myself purchasing regularly or that I require a high standard of quality for.
