They sell used as new.
Ordered a new "import" lens, received a used lens. "Passed" sticker was missing but I could tell where it used to be and there were tell-tale signs of wear in various places on the lens and lens bracket and some paint or sharpie action used on those wear areas. I knowingly purchased an "import" lens, but I suspect they took a demo lens, or floor model, repackaged it in a generic box with a generic label, and sold it to me as a new "import" model. There's no documentation in the box, no manufacturer information, nothing. No exchange was offered when I called them.
