can people selling things online scam you?

So I really want this nice jacket. Its from a movie and I have been looking for a good replica not a cheap alternative that doesn't look like the one from the film. I have been looking for a few days and I found one that looks exactly like it! But the picture is the same picture of the exact jacket from the movie that sold for over $20,000. Im really worried they are just showing that picture but then it will be a cheap plastic leather jacket that doesn't look anything close to the one in the movie. But its just a basic jacket anyone who knows how to make them could.

Can they do that? Can people selling things online show pictures of high quality items but they give you something crappy?
thank you guys for the great answers! :-)
