The following is a direct copy of an e-mail from CreateSpace. CS is offering a trial service to authors with multiple titles with CS. If I publish a new title between now and May 27th, I can skip the proof copy stage. This saves me a few dollars in the process of getting my book in print, but I always manage to find flaws requiring change in the proof copy. For the brave though, it will save some money.
As an experienced CreateSpace author, we need your help. In our continual effort to improve the book setup process, we want you to try a new option in your account. When you upload files from now through May 27, you can choose to order a book proof or skip the proofing process altogether.
As part of this limited trial we'll ask you to complete a survey about your experience. Your feedback is important, and it will help us decide if we should keep this option and invite more authors to try it out.
We look forward to hearing what you think!
