I have pre-approved offers for Amex personal platinum (100K sign-up bonus) and Amex business platinum (150K sign-up bonus). I would really like to take advantage of both offers by signing up on the same day, but am unsure if Amex will award me the sign-up rewards on both cards. I gather from one of the threads here (https://saverocity.com/forum/threads/amex-plat-ameriprise-and-amex-plat-signup-for-both-possible.164999/) that Amex did not award the bonus in a somewhat similar situation. I am new to the hobby and would appreciate any comments on this from the more experienced members in the community.
