Createspace

I am using Createspace for the printing of my book Connie Cobbler: Toy Detective.
I submitted a few more revisions after my initial round. I was told that I would be allowed 20 total corrections. I had not used all of my allotted corrections and believed that I would be able to use the remaining ones on the next round of proofing. I was told that the corrections would have to have been made on the original round. Createspace told me that I would have to pay $75 for additional corrections. While a compromise was achieved, I would suggest that you read their fine print very carefully and use more than one copyeditor.
