Do you have any proof they are not commingling? Have they outright said it at any point? Because there's more than enough anecdotes out there (and in previous threads about it on HN) that show that 1st party products are not treated any differently.
Amazon has to list the value of their inventory in financial reports. If they were commingling every single report would be a lie. Also, they explicitly state that: >Generally, we recognize gross revenue from items we sell from our inventory as product sales and recognize our net share of revenue of items sold by third-party sellers as service sales. If they were commingling, those figures would be a lie. The reason…
> If inventory that you have title to and inventory you do not have title to is commingled there is no way to track which of the two have been sold, who holds title to what remains and inventory, and what that is worth.
How is this not a problem for the 3rd parties with commingled inventory? Amazon clearly has a way to know which of the many 3rd party sellers they commingled sold the product in order to pay them, and know how many products are in stock across their commingled inventory.
Considering the product is supposedly the same, the cost would be the same, and they would only need to do the exact same tracking they do with 3rd party sellers whenever they themselves sell an item from the commingled pile.
By design, it is assured that the number of products you put into the system are the number you will eventually sell, even if it's not the exact same physical product. And that is totally fine if the products are identical and cost the same. That is the whole point of the commingling system; that the products are meant to be completely interchangeable. There's no accounting magic to be done, you're just tracking the number you sold vs the number you put in.
