I don't know what "evidence" you guys have that points at it being a switcheroo?
Just recently I saw a 10" Vinyl CC Jango Fett in a Darth Vader box. Box was sealed and all. It's possible.
Take into account who it is thats packaging these things.
To give the seller the benefit of the doubt, they have 99.6% positive feedback, 2,600 positive feedbacks, 600+ in less than 6 months.
They are also selling a slew of toys, which shows me that he isn't hurting for money. So, to be honest, none of us have the right to speculate, although we're enititled to our own opinion.
