Spend 40$ using bpme app and get 10$ back.
Saved for my two Amex cards without a problem.
Save the offer to your eligible Card and spend $40 in one or more transactions, via the BPme app at selected BP locations by 09/10/2018 to receive a $10 credit, up to 2 times. Limited to 30,000 Cards to save the offer. Exclusions apply.
Weird. Probably have to contact Amex then if you've registered and not received any qualifying notifications.
