From the website:
"Do your ears a favor with these audio adventures. The Humble Scholastic Audiobook Bundle features some of the hottest titles for your listening pleasure. Name your price for The Hunger Games, Spirit Animals Book 1: Wild Born, Infinity Ring Book 1: A Mutiny in Time, and Goosebumps Horrorland #1: Revenge of the Living Dummy. Pay more than the average price to also get Catching Fire, The Raven Boys: Book 1 of the Raven Cycle, The 39 Clues Book One: The Maze of Bones, War Horse, Goosebumps Horrorland #4: The Scream of the Haunted Mask, The Invention of Hugo Cabret, The 39 Clues Book Two: One False Note, and Infinity Ring Book 2: Divide and Conquer. If you pay $15 or more, you'll receive all of the above plus Mockingjay. Is that not the best bundle you've ever heard of?
In case you didn't hear, you can pay what you want. This collection of audiobooks would normally cost you more than $255 if purchased separately, but we encourage you to listen to your heart and set the price accordingly.
Listen anywhere sound can travel (sorry astronauts). These audiobooks are DRM-free and Multi-platform so you can download them onto your favorite device to enjoy wherever you go in MP3 format. They can play on your computer, iPads, cell phones, most e-readers, and a wide array of mobile devices meaning you can listen to them anywhere at anytime! Instructions and a list of recommended reading programs can be found here.
Support charity and sleep soundly. You choose where your money goes — between the publisher and Feeding America, the nation's leading hunger-relief charity! If you like what this bundle has to offer, a tip to Humble Bundle is not unheard of (and definitely appreciated)!
It's quite annoying with the tiers. In order to get all Hunger Games titles, you would need to fork out $15 to get all 3 audio books.
