> For context, concealment is bad here because co-mingling means Amazon doesn't even know which vendor shipped the defective product That is not true. From Amazon documentation on commingling: > Note: Amazon ensures that the initial source of the commingled units can be traced throughout the fulfilment process. > How does Amazon track my commingled inventory? > Even though your inventory does not have additional labels, Amazon will assign a virtual trackable label to your units once they have been received. Virtual trackable labels allow Amazon to keep a track of your inventory at all the times. > Important: Amazon ensures that the exact same units from two sellers, participating in the commingling programme, are always physically segregated. This means that Amazon storage logic does not allow same ASINs of different sellers to be stored in the same bin in our warehouse if they are commingled.

Can you please clarify this a little more. I thought I read in HN many times that commingled items can be supplied from any vendors supply and not the one a buyer chose. What does it mean that they track it but don't ensure that proper items are delivered and what's the advantage of amazon to commingle. Another thing is if Amazon actually fulfill one buyer's sell through another's supply how is this not a fraud by amazon and how they are not sued out of business even without any fake item issue? This is one thing I never understood.

  > I thought I read in HN many times that commingled items can be supplied from any vendors supply and not the one a buyer chose. Correct. > What does it mean that they track it but don't ensure that proper items are delivered It means Amazon can send an item originally supplied by any seller, but Amazon will know who the original seller was. > and what's the advantage of amazon to commingle. Reduced fulfillment cost by e.g. having the stock closer to the buyer and reducing the need to ship orders from multiple warehouses (due to orders containing various different products and/or different sellers), as they have more inventory of that product to distribute throughout their warehouses. > Another thing is if Amazon actually fulfill one buyer's sell through another's supply how is this not a fraud by amazon and how they are not sued out of business even without any fake item issue? Both sellers have agreed to commingling. When you buy from seller A but seller B has stock closer, sellers A and B will perform a trade (automatically) where A gets one item of B's stock and B gets one item of A's stock. And then the now A's item will be shipped to customer. So at the time of shipping it is A's item, as the customer ordered.
