Is that even a thing? I’ve never heard that being possible before. I would be willing to pay a premium for guaranteed non-commingled products. But Amazon commingles to make their own internal logistics easier.
According to [1] if the product has an EAN/UPC/ISBN barcode, it gets commingled, but vendors can put a sticker over it with a different barcode to prevent commingling.
Or the FBA label service [2] can apply the stickers for you, at 0.15/item
If they offered this option it would be an admission on Amazon's part that they know about the issues with co-mingling (which of course they must do by now, but they wouldn't be dumb enough to publicly admit it).
