I've never done it on Amazon, but I have unpublished a version of Glimmer on Barnes and Noble. It went away from the site almost instantly, but it is still in my line up on my dashboard and there isn't anyway to take it off.
I unpublished it because it was all garbled and converted weird and I needed to start from scratch.
