Are you sure you added it to your other cards before you added it to the first card? You have to add it to your cards simultaneously with multiple browser windows open to the offer before you add to any card. I've added the Overstock and the Glasses.com offers to all of my cards and I've used Overstock twice and Glasses.com once and they are still showing up on the other cards I added them to. All of my cards are within the same online account.Amex throwing us a curve ball with these new offers.
I had the overstock offer on 6/7 cards in one of my online accounts. It disappeared on all of them after I used it last week. Thought it was a glitch but sure enough, the T&Cs spell out what's going on.

This might be a case of the new crappy site format. How does one revert to the old view?
walmart, overstock, a few others:
Limit 1 statement credit(s) per American Express® online account.
majority of prior offers:
Limit 1 statement credit(s) per American Express® Card across all American Express offer channels.

Where all cards in under one login or did each card had their own login?When ever I load up AMEX offer and get it for 2 or 3 cards, I only get credit on 1 of them once I make the payment. I contacted AMEX once about it and they basically said "too bad, only 1 per account, you should have known"
