Instead of buying all of the books and posters individually, why not buy the bundle at a cheaper price?! 
This bundle holds the shortcut booklets for Adobe Illustrator, InDesign, and Photoshop, while also holding the 11x17 posters for these booklets. It also comes with stickers inspired by the character designs!
Bought separately, the total comes to $105, but with this bundle, it is only $60!
