I ordered a Noctua CPU cooler from Amazon a few years ago. It was sold to me as new, and it definitely looked new, but when I opened the package to the it out and install it, it was missing several components. It had obviously been opened and either used or at least taken apart, then put back in the packaging.
I didn’t feel scammed necessarily, but it was extremely annoying. I had no trouble with Amazon taking it back and sending me a new one. Honestly the only reason I think you’d have trouble is if your account has a history of questionable or large returns.
