For some reason clicking on the link brings you to the regular chroma, you can get the X, just non chroma.
(First link: https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=Razer+Blackwidow+Chroma+X, but it links to a normal chroma).
At this point, I would contact amazon about that one.
