My source for getting the AmEx Platinum from GS has come up empty, not even current employees can get the card (according to the source)! On top of that I became a GS shareholder just to get a crappy printed out participation award quality certificate:
instead of this one:
I even emailed the good people at Give-a-Share and they conformed they went full crap! I called shareholder services and no one had any idea of how to get the card. If you are itching for another AmEx Platinum I suggest applying for a lower product such as the Green or Premier Rewards Gold and upgrading after a year.
Use this link for PRG if you go this way.
