Input: Consider Input: I was excited to get this book, it looked like such an awesome deal. But as soon as I put my order in they canceled it and sent me instead. It took them three days after they told me we wouldn't be getting the book. Terrible experience. They also just cancelled the first one over night. Amazon needs better tracking systems.
