Rita;
I called the number given for customer service. It was very late at night and they still answered and talked to me (REALLY, a PERSON talked to me, WOW!). Amazon has given me MORE than excellent service in the past - they seem to be a real customer oriented company. At least, that has been my experience in more than one case.
While exploring the Amazon web site, I discovered a "used, like new copy" that shipped with my Amazon Prime for $7.38. Now, I KNOW it was probably a "one off" but if you look around the web site regarding this book, you will find some good prices considerably less than Amazon's regular price.
I'll post if I get any results on the reformatting for our Kindles.
