I don't have the answer... but I would like to expand the question. I am new to Kindle and have just sold my first book... Yea! What I would like to do is design a web page on my website that gives a full review of my books and embed a link to my book in the Kindle store.
How do I find the url to link to my book in the Kindle Store?
Do you see your book in the kindle store? Do you see that URL above in your web browser? Technology allows you to copy and paste that link anywhere you want to. You can copy it into your blog, twitter, or facebook page. I like to copy my URL's to notepad or even a word doc. Save the file so that I can always have them to copy into other places places. If your URL is a hundred characters long, you can use from among several URL shorteners to make it into something manageable.
