This information below was on the original flyer we sent to everyone about the promotion. I note the ID code that JOanna got was the same as we were told BONUS ID 6469.
However the next numbers were different.
Joanna's BONUS ID # 6469 and Offer ID # S534:0001
We were told Bonus ID: 6469 Offer Code: CAMX MR25
If one does not work try the other.
OUR ORIGINAL INFORMATION
If your card qualifies and the points do not post to your Membership Rewards account, you will need to contact American Express directly as they will not release information to us regarding your credit card or rewards account. As noted above, this is only for American Express Rewards cards only. The American Express contact information provided for this promotion was 800-EXP-EARN Bonus ID: 6469 Offer Code: CAMX MR25
