I received this offer in the mail. I don't have the offer code any longer. However when I entered the offer code, my information appeared. Interestingly, I have a personal Amex and I had an Amex business card for another business that I cancelled for the AA 75,000 mile card. The previous Amex business card has the same office address as the new one and obviously the social security number matched. The new one is for a business that has very little in the way of expenses.
I am very pleased to have gotten the offer.
