Ex: amazon sells tshirt. People post reviews. 3rd party sells tshirt with the same product page as amazon's and the quality is poor. Reviews are mixed together and you can't see the seller on which the review is based.
It's a bit fraudulent really, like a bait and switch.
In reality each page needs a product and supplier rating, and people need to be guided to rate both. Instead you get "this company sacked my daughter; 1 star" and "the postman dropped it; 1 star" type ratings.
Reminds me of story where (and I'm going to butcher parts of this) a town is making a huge vat of wine (or maybe it's food related) and everyone household is supposed to bring a bottle to pour in. A couple of people decide to cheat the system and bring water instead expecting to hide under the radar. It turns out way more people than a few take this path and so the "wine" just tastes like water with a hint of wine in it.
As it's Amazon, presumably they tested and found this to be the best mode for profit.
Is it really identical? They do have quite a bit of warehouse which means that shipping can be quite longer and more expensive.
Let say I'm a third party and I got 100 shirts in Amazon warehouses in north America and they got 100 too. That means that in average there's 2.6 shirts per warehouse (I found there is 75 warehouses but that can be a wrong number) but we each got 1.3 in averages! If someone buy 2 of mine, most likely they'll have to ship one from somewhere else, while they could just take one of theirs and consider it the same.
At the end of the day though, it doesn't means that I was truthful and my product is actually the same, which can hurt their orders.
There is a separate review system for sellers, and the score is shown when you look at the buying options, but it's little used and much less visible.
There's still a measure of control in who the supplier is, and the reviews for that supplier too.
I would say "no," because pretty much everyone I know thinks Amazon is a store with a single source of goods, not a "marketplace." This is probably intentional.
I haven’t ordered from Amazon since I learned this months ago, with two exceptions for birthday presents.

However let's say you want to buy a product. But the reviews are mixed. Some are 5-star reviews, but there are 1-star reviews as well. And there are 5 sellers. From which one do you buy? All the reviews are mixed.
Perhaps a bad review is caused by a seller sending fake product. But perhaps the review is a valid review and it highlights a defect in the original product. You can't know.
Then it was updated to include "nothing that goes on or in your body."
Then it was updated to include "nothing that goes on or in any living thing."
Then it was updated to include "nothing you wouldn't by from a random stranger standing outside a fly-by-night flea market."
For thousands of years, brick-and-mortar stores have lived and died by the quality of their merchandise. Amazon is just learning this.
But because Amazon is hitting conventional, traditional retailers so hard, now I have to wonder: could Amazon's behavior with regard to counterfeit products and commingling influence my local brick and mortar retailers to do the same thing?
If it's branded and there is a decent profit margin, i guess we should assume some questionable actor will steal that margin given the opportunity.
There are some questionable things going on with dog food as well. For example I recently purchased a case of a certain dog food my dog has been eating for years. If I click on the product link in my Amazon order history it says that it is sold by the manufacturer of the dog food, but in the Amazon order history itself it says a different store that I've never heard of. The inside of the can looked a little different, less gravy and it made my dog start vomiting almost immediately.
