Hm, and now I'm in a similar boat as
@wendow .
Since hubby is staying at a Marriott for work this week, I sent him with my SPG card that has the Spend $200 get $40 back offer. He'll put $200 on that card and the rest on his Marriott card (for convenience, since I'd just be transferring the points to his account anyway). Evidently he asked at check-in to put the $200 on that card, so they charged $200 on 7/21 (fully posted, not a hold) and it hasn't triggered the offer yet
The offer is still showing in my Saved offer list like it never happened. When I checked the details of the transaction it's got the stay dates listed so it should have come through correctly as room and rate charges. I think as of Tue it was still a pending transaction so maybe needs some more time after it posted? Usually it's been pretty good with the emails with just a pending charge but this is the 2nd or 3rd offer I didn't get notice. Don't know what's up with AmEx lately. I'm hoping it'll catch up eventually.
