American Express Sync + Xbox Promotion

Here is another American Express Sync promotion if you sync your AmEx card with your Xbox LIVE Gamertag on Xbox 360. Visit AmeXbox.com to register. At the very minimum, you’ll get $10 for registering your card at AmeXbox.com, with more lucrative opportunities if you have Halo 4. As with other American Express promotions like Small Business Saturday, I assume you can get $10 for each card you own including authorized user cards, if you have multiple Gamertags. I don’t have an Xbox, but reader Nic helpfully sent me the e-mail text below.

American Express and Xbox are bringing you a new way to save. From now until December 31st, Cardmembers can sync an eligible American Express® Card with their Xbox LIVE Gamertag to unlock exclusive content, offers, and more.
• Spend $10 at AMC Theatres®, get $5 back
• Spend $50 at PacSun®, get $25 back
• Get a $10 statement credit from American Express

Cardmembers who sync their Cards with Xbox LIVE and play the newly released “Halo 4” will also be able to unlock additional offers by reaching specified in-game achievements. These include:
• Spend $100 at Best Buy®, get $50 back
• Get a $25 statement credit from American Express
