If you have something with a UPC code, say the DVD Back to the Future, the latest edition... it will get put on the same shelf as other people with the same identical product, with the same identical UPC.

They aren't just dumping all DVDs in a big pile and picking out a random one.. its for literally identical products.

Does someone pirate DVDs and put the proper UPC on them? I guess it might happen, but how often? And if it did you tell Amazon and get a full refund and the seller is banned.

I can see reasons to not trust Amazon (the fake reviews, etc), but commingling of sealed goods is not one of them.

Yes. That's called counterfeiting.

And by the way yes, I understand how commingling works, and Amazon says they will not do it with DVDs. I understand that Amazon says they can trace who provided the goods I receive. That protects Amazon. It does not protect me.
