Probably a scam on a 7800x3d, but wanted to make sure

So I was looking to buy a used 7800x3d, but gave up after not finding good enough deals. So I went to amazon, and saw that the 7800x3d was 20% off for $359, and bought it immediately.

I thought it was legit, since it was the first result when I searched for it on amazon. It looked like this picture

I didn't take a picture when I first saw it, but I did purchase it directly from this page, or a page just like it, with a 20% off by the seller called Xinwei art. I thought I got a good deal, but it didn't seem to be to good to be true since the 7800x3d did go for around $350 on sale at one point.

Then I thought a bit more, and got worried it was just junk, so I looked at the sellers page.

Clicking on "visit the xinwei art storefront" leads to a blank amazon page:

And going to their detailed seller info gives:

That very long business, the complete lack of any real reviews, and no other actual products, its a tell tale sign of nonsense right? Or am I just overly paranoid? I also have the original link that I was when I bought it if anyone cares.
