Wow, HN is really turning into a hive mind. First time I see someone post this. Thanks for this data point.

With this in place, it seems vendors get to choose if they want commingling or not. Would be nice to provide a checkout option to buyers as well, like choose a slower shipping but guarantee your getting the item from the vendor. Or even if it asked you... getting item from alternate vendor will ship faster? Is that okay? And mentioned the alternate vendor.

Except go read the seller's forums. Sellers who (claim to) opt out are constantly complaining that their product still gets mixed in. Even sellers who do their own asin / personal barcodes have problems with it.

Amazon is either ignoring the preference when it suits them, or has significant flaws in how they're implementing the policy.

Either way, they're destroying their brand reputation.
