Okay, I’m a little confused by this freebie, but I am going to share it anyway. Have a look at the deal by clicking here. Apparently, if you fill out an Amazon review of this product and then apply at this site, they’ll send you a FREE battery case for the iPhone 4 or iPhone 6. Now, I’m not exactly sure how you review something before you have it. I also don’t know why the iPhone 5 is not included. If you decide to do this, come on back here and let us know how it worked!
