THE NEWS: American Express is rolling out a Facebook application to offer cardholders deals based on their profile information on the social networking site.
THE PERK: Unlike Groupon and LivingSocial, cardholders don't have to pay up front to get the Amex deals. There's no penalty if cardholders never use the deals they select.
HOW IT WORKS: It's not clear how personalized the Amex deals will be in the beginning, since the Facebook application is launching with offers from only about 100 national retailers. But Amex says it plans to quickly start adding deals from local merchants in coming weeks.
