It’s worth pointing out the cracks in a service everyone uses - some of those cracks have been there for a long time and Amazon has been doing a poor job combating it - if they even are. Amazon seems to make knockoffs themselves of best selling items, but that’s another topic.

To your point though, depends what you buy - when I was looking for really good headphones a few years ago, there were warnings on review sites about ordering Sony brand headphones and getting fakes. Apparently there were also sites dedicated to help identify fake headphones bought from Amazon (Sony MDR-7506). Once would be correct to say counterfeits were around since before Amazon, but you wouldn’t expect to get a counterfeit if you pay full price from a brand name store - which is the new problem.

Also buying SD cards, specialized batteries, etc has been a big problem on Amazon for years, and Amazon doesn’t seem able to really address it (inb4 someone says they haveade it worse)
