Use the following code in the mobile app to make the case free (Exp: 9/30): APPCASE

You can currently stack both of these codes. Last time there was stackable Shutterfly codes for free items the deal was honored, but the codes stopped stacking before the expiration date, so take advantage while you can!
Post what other stackable deals you find with the current free shipping promo!
