Chapter 7 Free?

Amazon very recently announced the "Pre-Order" option for self-published authors. I don't expect anyone to pre-order my work, but it creates an Amazon listing for the title ahead of time so I went ahead with making Chapter 7 available for Pre-Order. However, KDP (Amazon's Self Publishing interface) has locked me out of editing any of the book details or promotions (to list the book as free). Furthermore, I can't even VIEW the details or promotions. With that said, I believe Chapter 7 will be available tomorrow. However, I am not sure that it will be free. At the very least, it should be free on the 16th. Sorry for any inconvenience.
