Why isn't your book published also as "paper" book? What's the difference between the "multimedia CD" and the Kindle edition (besides the price)? Does it mean there's no way to download the code listed in the book if you buy the kindle version?
It confused me as well when I was looking for an appropriate link to add to our overview of OCA 7/8 study materials. I thought I had the wrong resource, but then I verified the ISBN with the one on the publisher's site and they both match. So maybe it's a bug on Amazon and they selected the wrong format ("CD" instead of "Paperback").
