(DEAD) MONEY: For AMEX Credit Cardholders — get a $25 AMEX gift card for $15 only via Sync Rewards

American Express via their Sync Rewards has a new reward where synced American Express credit cardholders can buy a $25 American Express gift card and get $10 back on their credit card statement. That’s essentially $10 for free since we’re talking about a cash gift card here! This is a great way to get the most mileage out of your American Express credit card, especially if there are any annual fees associated to it.

To get in on this offer:

• You MUST have an American Express credit card or charge card. Prepaid cards and gift cards are NOT valid for any sync rewards.
• Make sure you have registered your card with Twitter at sync.americanexpress.com/twitter
• Follow @AmexSync on Twitter
• Tweet a message with the following hashtag: #BuyAmexGiftCard25 
• You should receive a confirmation message from @AmexSync asking you to confirm the purchase for the $25 AMEX gift card using the AMEX credit card you synced.
• You MUST reply back in a tweet with #ConfirmAmexGiftCard25  (note: this will confirm the purchase of a $25 gift card for you on your AMEX credit card!)
• Your confirmation message may actually be a custom link to update your shipping information if AMEX does not have that info linked for your Twitter AMEX Sync. 
• The gift card will be mailed to you in a few days. You should see the statement credit automatically reflected on your statement.

See sync promotion page here for full details.
