Strange...
Alfred Music lists a single volume "Complete Ukulele Method" with an accompanying CD that covers the three books (Beginning, Intermediate, and Mastering Ukulele).

Though, that doesn't include any DVDs! What's the point? I bought the three books separately and each has a DVD with video examples. I believe the mp3s are on the DVDs as well. Way better to have the DVDs, believe you me, than just an audio CD. It's great seeing Daniel Ho in action on the uke. Though on the Advanced DVD, it doesn't follow the book in order of lessons. It jumps around at one point, but it's all there.
Here are the ISBN (International Standard Book Numbers) so you can look them up in any site where you like to buy books or order them from your local bookstore even.
1) Beginning Ukulele 978-0-7390-9548-5
2) Intermediate Ukulele 978-0-7390-9549-2
3) Advanced 978-0-7390-9554-6
