American Express has another sweet deal through their Facebook Sync and Twitter Sync programs. Another great way to save some money to put towards travel.

Simply tweet #AmexAmazon to get $25 statement credit with at least a $75 purchase through amazon.com through December 31, 2013. The terms and conditions seems to suggest this can be a cumulative total.

UPDATE: There is now a direct link to sign up without having to use Twitter. https://enroll.amexnetwork.com/US/en/Amazon/

Receive a one-time $25 statement credit when you spend a total of $75 or more online at Amazon by 12/31/13.

Here’s a recap on how to setup your American Express cards via Twitter.

Step 1: https://sync.americanexpress.com/twitter/Index. I create a separate Twitter account and corresponding gmail address for each registered Amex user.

Step 2: Tweet #AmexAmazon. To manage all of my Twitter accounts, I like to use a free Twitter client like TweetDeck. It gives you the ability to tweet from all of your accounts simultaneously.

Step 3: Confirm that you have the offer by clicking on @connect

Step 4:Spend a cumulative amount of $75 on amazon.com by December 31, 2013.

Step 5: You’ll receive a confirmation email shortly after your purchase letting you know that you’ve saved $25 by using your synced card.
