I found a few out here in Los Angeles.
If you present your card at South Street Philly Cheesesteak in either Burbank, Westwood, or at Dodger's Stadium, they will charge you double.
Present your card at any Los Angeles Barnes & Nobles and they will GIVE you the book of your choice, if you promise to take at least five items from the clearance vestibule.
If you present your card at the W Hotel in Westwood on a Wednesday, Thursday, Friday, Saturday, or Sunday night and plan a wake-up call later than 6:30am, 2008's Rookie of the Year Steve in North Hollywood will wake you up by nudging you.
