Counterpoint: People do this on Amazon all the time. One time I ordered a kick drum stand on Amazon. All I got was the foot of the stand and a brick in the box.
It was supposed to be brand new, not a used item.

For me, living first in Baltimore then NYC, places where there's quite a few people buying quite a few things up and down the cost scale, I never saw a counterfeit anything come up.
That's not to say I think it doesn't happen, just that I think that's why some people have wildly different experiences here.
