Hrm, dang. Seems my grand plan wasnt to be... not sure if its due to Amex wising up, or due to my credit history starting to show signs of cracking.
Tried to apply for the David Jones Platinum Card via referral link. Advised could not hold both DJ cards at once so cancelled the DJ Amex, and proceeded with the application. The T&Cs of the Platinum card specify only the Platinum DJ Card as being a reason for not qualifying for the bonus points... so figured it was worth a shot for potentially 90,000 DJ Amex points (30k referral to mrs tizey, 60k to me)
Turns out not to be - application denied. Oh well, nothing ventured and nothing gained. I do wonder if the DJ cards are assessed manually and thats why rejected?
