There is a new feature for your books on Amazon. Or any book, even on you are reviewing. You can embed that take a ‘peek’ right into your post.
On blogger I was getting the embedded review box. On WordPress it wants to open a separate window with a larger review box in it.
Either way the review button is at the bottom.
It would be easy to insert this in a promotion of your book or into a review of a book to give a take of the book you were talking about. I’m glad I noticed that can do that now. The things you figure out late at night randomly staring at a computer.
