Indeed, I'm not even sure that Amex would know you had a bank card (though they may do shortly with CCR), and for example the DJ's card may be an Amex (and even Amex operated) but DJ's are the main customer "owner".I've had luck in the past with co-branded cards ... never tried to get a bonus on two actual Amex supplied cards. So, for example, had a plat edge and a corp green charge, applied for a velocity and got the points. I think I had a bank branded amex when I applied for the Plat Edge too and got the points for that one as well.
