Anyone that listens to audio books might be interested to know that Amazon has now been offering an audio book version through Audible at the same price of the ebook, when you purchase an ebook. I've bought two different ebooks recently for around $3 a piece. And, after I make my purchase, there's an offer to buy the audio book at the same price. I tend to listen to audio books at work. But, my wife prefers to read them on her kindle. So, for my situation it makes sense to have both. But, usually when you look at the prices of Audiobooks they're well above $10, so even if you just wanted the audio books, this is still a great discount.
