Food Therapy: Dunkin' Donuts & Amex Blue = $5 DD Gift Cards!

If you're more of a Dunkin' Donuts fan rather than a Starbucks fan, and you have an American Express Blue, this deal is for you!  Make 4 separate purchases at DD in a calendar month with your Amex Blue, and receive a $5 DD gift card in the mail.  This promotion runs through 3/31/2011.  There's one catch:  you must register your Amex Blue for this promotion.  To do so, click here:  DD & Amex Blue Promotion.  (Note:  I think you can earn more than one $5 DD gc per month.  It's not completely clear.)
