A targetted offer of an Amex Premier Rewards Gold Card with 2 years of the annual fee waived and 50,000 bonus points is making circles online. It’s an incredible deal, however it is a targeted promotion for Columbia Business School 2011 and 2012 graduates. Also people who have an Amex charge card (Platinum, Gold, Premier Rewards, Green or Zync card), are not qualified for the bonus points. Folks on the flyertalk have reported success with this offer. As always take screen shots and call the membership rewards team to confirm the offer after the card is activated. Amex generally has good customer rep service and would allocate you points generously.
