Freddy's Frozen Custard and Steakburgers sends its Rewards members a surprise reward on their birthday each year. The item is not named publicly - it is a genuine birthday surprise.

The account is free through the app or web; just provide your birthday when you sign up. The reward must be used within 30 days, and if your birthday falls within 30 days of signup, you will receive the reward the following year instead. Most locations participate (airports, venues and campuses may not). Request this Freebie
