Pizza Rev is offering a free pizza or salad if you download their Pizza Rev app from the Apple store or Google Play and then join Rev Rewards.
1. Go to Apple store or Google play and type in "Pizza Rev."
2. Download and install the app.
3. Open app and join Rev Rewards. Within 3 to 12 hours you should see the free pizza or salad by clicking "Redeem" when you open the app. If you used Facebook to sign up you also get a 10 point bonus.
I got my bonus within an hour but it could take up to 24 hours (YMMV). Pizza Rev is very similar to Pieology where you pick your own toppings. Enjoy the free pizza.
Thanks to Asylum for posting the states that currently have a Pizza Rev:
