Well I created and uploaded an e-book Kindle, to Amazon and was notified that it was available, at this link: Through the Mists
I immediately had a look, and for the very first time ever, I noticed it was in fact not available, and the comment was that "Pricing information not available."
I waited a day, and went back in and edited it again, and confirmed that pricing was all correct, and then got an email from Kindle on 21st Dec identical to the earlier one, and yet again there is the same listing, not available, "Pricing information not available."
I guess I will wait a week or so, but I have never had this problem before, and all territories are offered. I am based in Aus, but have not had any problems buying Kindle books, in fact I bought one yesterday. I would have published 6 or 7 e-books without issue previously.
