The Amex synching promos continue!
Now, they span from Twitter to Foursquare to Facebook! see: https://sync.americanexpress.com/
And, just when I was yawning at the Twitter Synch promos- they came out with a good one! Spend 10 dollars at BestBuy, tweet, get 10 dollars back on your statement!
Keep ’em coming!
