Can this promotion only be done once per Amex Platinum card?
I did it when I opened this card and got the 5 bonuses after spending 4k on each, almost 2 years ago.
I didn't think anything of it and added an additional 5 AU's when this promo came out ~ 9/23. First AU finished spending a few days ago and points haven't posted. Now I'm starting to think maybe it's only once per Platinum card?
