As some of you already know, I have some pre-made ebook covers that I sell really cheap ($25). Are they super unique? Not really. Are they better than you can make yourself? Probably. And I personally won't use the same image on someone else's cover.
So if you've got a sci-fi epic and your cover is some earthly clouds in a solid colour KDP template, looking like a collection of angsty poetry (yup, seen it), I might have something slightly more science fiction-y for you!
New covers are added regularly! Sci-fi not your bag? Check out other genres on my pre-made covers page!
