Wait, how is this different with eBay compared to Amazon?

So if two sellers are selling the same item, with the same exact SKU, and both send their inventory to Amazon to be warehoused and shipped, Amazon will happily send you either seller's item, depending on which is more convenient to send. (Perhaps seller A's stuff is in a warehouse closer to you.) This sounds good in theory, because all those products are identical, right? What if seller B's products are all counterfeit? So you buy from seller A who you think is legit (and for the example is), but you get seller B's fake crap, and seller A was powerless to stop it.
They could select the "Amazon barcode" option (instead of the default "Manufacturer barcode") under "Barcode preference" which prevents commingling (but requires the seller to apply seller-specific barcode labels to all units).
Amazon's checkout process is 99.99% in the Amazon context, only showing a "sold by" on the order page itself in a 12px font. There is no mention of the seller at all in Amazon's order notification emails.
