There's just something about unearthing a new birthday freebie that puts me in a great mood. It might have something to do with all the free pizza I'm about to get next month.
Cici's free birthday pizza is an offer that's easiest to acquire via their mobile app. You can sign up for their email, but if you really want this, I'd suggest downloading the app. Then, when your birthday rolls around, the freebie should be in your Rewards section with a two week window to use it.
