That also may be true. But they would not be ordering from Amazon! They would likely have their own accounts at the fashion houses - Givenchy, Chanel, etc.
So any person trying to sell an overpriced item on a non-specific website is automatically guilty of something illegal?
My entire point is that sometimes people will ask ridiculous prices because....they can. It does not mean they are doing anything illegal, frankly I would say they are being ridiculous.
