Amazon Redesign

So here's the thing... I love Amazon. Hit the buy button, and two days later I've already got the item in hand? Incredible. Their mobile app design? Not so much...

Just for fun, I thought I would take a stab at simplifying the design, and hopefully improve the form AND function.

Let me know what you guys think!
(PS. Check out the attachments for more detailed views of each of the screens I redesigned.)
