As you can see in the image above. It’s pretty self-explanatory. But allow me to explain a little further. First of all this is a contest. So, not everyone is going to get a PS4 for free only one lucky winner is going to win a PS4. To enter all you have to do is download Amazon’s mobile app and sign in. This contest will start on 14th of July and will end at midnight of 3rd of August.
