Unable to download iWork apps with my new iPhone 5c

So I recently purchased a new iPhone 5c from the Apple Store a few days ago. When I launched the App Store, as expected it asked me if I wanted to download the iWork apps. I hit "Later" and it took me back to the App Store. Now, I would like to download them now. I cannot find an option to and when I look for them in the store it says the price of the apps and not "Free." Is there a way for me to get these apps for free or do I have to pay for them? Thanks!
