I'm surprised no one has mentioned this here.
AmEx sent me a later today stating that my cashback is being reduced. From October 1st this year, they'll be paying out (annually, again):
0.5% cashback if your total annual spend is 2,001They've also decided to change various other aspects of the Blue Card service. For example, money back cannot be earned if it totals < 5 over a year. Also, the standard interest rate for balance transfers (after initial six months of having the account) changes from 9.9% to 12.9%.
So, is it time to get the American Express Platinum Credit Card? I've had my Blue card for just over three months now and have so far spent just under
4,000.
