Not sure why it isn't available to you. Every week or two, I get an email from AMEX with various offers I can opt into by "registering" my cards for that offer. The Brooks Brothers offer was one of the ones recently available. You may want to call AMEX to inquire about it, as it's a painless $50 credit.
