Anyone know anything about this? Apparently it is not one of their "sync" offers. https://rewards.americanexpress.com/olet/splash?campaignId=bklt1114&offerType=multiplecardbklt0001# I stumbled upon it while surfing the 'net. I called the 800# and tried to enroll, but it said my card was not eligible for the promotion. Maybe others will have better luck.
