I was browsing some of the books on the main page for the kindle books
http://www.amazon.com/kindle-store-e...node=133141011
and took at look to see if I could find the tags. Sure enough, several of the books had it and are now $9.99. I wonder if the tag had anything to do with it?
Then again there is a book towards the bottom called The Mermaid Singing that the list price is $6.99 and the Kindle price is $9.99 though I am hoping that is a simple typo.
