If you have a normal (e.g. not corporate/prepaid) American Express, you can join in on Amex Sync deals!

You sign up either on AmericanExpress.com (when you're logged in) or on Facebook or Twitter.

There's a good one happening right now with Costco.com. Spend $115 and get a $15 statement credit. There are also $5 statement credits on Old Navy, Kohls, Toys R Us and Chevron purchases. There are also $50 credits for bigger purchases at Tory Burch, Coach, Neiman's, etc.

Did you know what Amex Sync was?
