> Did you know counterfeits can be sold under the “sold by anazon.com” branding because of co-mingling?

I have also had a bad experience with "Sold by Amazon.com" so I'm not questioning the veracity of what you are saying. But how does this work? How can someone get a counterfeit product under this umbrella?

"Sold by Amazon" comingles identical SKUs from different sellers in their warehouses.

Seller A sells real Product Z on Amazon. Seller B sells fake Product Z on Amazon. When you order Product Z that is "Sold on Amazon" you might get a real one provided by Seller A, or you might get a fake one sold by Seller B

I believe what you are saying is possible for “Shipped by Amazon” not “sold by Amazon”.

I believe your description was accurate before ca. 2015, but at some point they reportedly started making commingling the default even for "Sold by Amazon" items. Commingling isn't the only issue, either; there's still the problem of products for which Amazon was never an authorized retailer and so their listing/SKU may have been created to sell counterfeits in the first place. In any case, there have been multiple lawsuits specifically alleging that counterfeit items were "Sold by Amazon" [1] [2] [3].

My understanding is, if I sell an item with a SKU[1] 123456, and use "fulfillment by Amazon" it goes in an Amazon warehouse in a bucket with all the other items of the same SKU using Amazon's shipping. Then my inventory becomes just a number in a database.

People selling DVDs on Amazon were complaining about bad reviews because someone bought from them, but got a counterfeit sold by someone else.

I mean literally the next sentence after your quote says "I've never had any issues with fakes that HN complains about all the time" so I'm pretty positive they do know about it.

> How are you so sure you’re not getting ripped off?

If you do not _feel_ you've been ripped off, does it matter?

Just because you don’t realize something gave you cancer doesn’t mean you can safely ignore the cancer.

Feeling like you got ripped off is one thing, having your house burn down from faulty electronics is much worse etc etc.

bought an apple charger, nearly set my house on fire. I opened up the one I bought from amazon, and the old one I had at home. weight, number of components, etc clearly told me it was a differnt product. Yeah I was done buying anything electronic from amazon.

Yes, as it is preying on the clueless

Yes. I bought a ladle from Amazon. I noticed from some of the comments that a lot of people were getting a knock off ladle.

When I arrived, I checked to see if it was legitimate, and… it was not. It was a knock-off.

It was fine as a ladle. It ladled things. I never would’ve noticed or complained if I hadn’t seen the rules. No harm, no foul, right?

Absolutely not. That day I made a rule that I do not buy anything that goes on your skin, in your body, or health and safety kit from Amazon. If I can’t trust their ladles are authentic, I can’t trust their sunscreen or thermometers are authentic.

So, while the ladle didn’t harm me directly, it did pretty significant change my purchase habits.

Well, you don't know that the ladle didn't harm you directly. If it's made of substandard materials that leech carcinogens into your food, the effects might take years to appear.

Or anything that involves electricity.
