Overstock had the cheapest price anywhere,believe me I looked everywhere before purchasing. These are great , I have a hyper child that will not sit still for anything. I put one of the cd books on and he doesn't move until its over. He has also received the books and he is so interested in them that I think these will make it fun for him as he learns how to read. He is 6 and in Kindergarten. What a life saver, thanks overstock.
