AMEX Offers: Spend $30+ at Exxon Mobil, Get $10 back

If you have an American Express credit card, logon to your account and check the special offers. One of the latest making the rounds is a promotion that gets you $10 back as a statement credit if you make a purchase of $30 or more at Exxon Mobil gas stations by 12/31/15. You have to manually add this offer to your credit card.

Once added, this offer expires 12/31/15. However, if you don’t add it to your card, it can disappear from the available offers at any time. This is because of two restrictions: there is a limited number of sign-ups per offer, and the offers may also have a limited runtime of their own regardless of the sign-ups. So, to summarize, when you see an offer you may perhaps use in the future, add it to your AMEX card right away!

TIP
If you have multiple AMEX cards on the same account (in other words, the same login account), pay attention to which account number you add the offer. It will only work if you use the card with the offer on it. Otherwise, no luck and customer service won’t fix it for you.

Note also that a lot of the offers are only shown to a subset of their cardholders. So you won’t have available to you every single offer you see mentioned on the internet. How AMEX decides to offer what to who(m), I do not know, it’s probably part of their “secret sauce” targeting system.
