To enroll in these promos through Twitter, cardmembers must first connect their Amex with Twitter, tweet using promo’s hashtag, then receive a response from @AmexOffers stating that the offer has been added to your connected card. Once they have received the response from @AmexOffers, they must then use their card to make the required purchases within the offer period.

As with most other Amex Offers, if you don’t want to sign up through Twitter, you can also register for this promotion through other channels:

• Your AmericanExpress.com account – Log into your online account and click on the “Amex Offers For You” tab. Click the “Save Offer” button next to a deal to enroll your card.
• Use the American Express iPhone App and visit the ‘Offers For You’ tab in the ‘Membership’ section
• Through Facebook at amex.co/facebook

If you log into one of these other channels, chances are you’ll also see many other Amex Offers that you can sign up for as well. While Amex / Twitter deals are universally available to all eligible Amex cardmembers, the other channels will also include promos that are targeted to your specific account.
