I would be leery of any of the Disney titles that are "in the vault." I bought a Peter Pan from a seller with many DVD sales and positive feed back. It, and I imagine all the others, was not legitimate US editions. The other buyers did not know the difference or did not care.
You could ask "if it does not include the Magic Code, will they would pay return shipping and refund you the cost of the movie."
Once in a while I see one that has a special attachment, like a pin. I assume these are real, but they sell really high.
