Tweet and get paid, seriously.
Well, in the form of $$ credits back to your credit card, but, money is money right?
Amex launched Tweet your way to savings and it's ridiculously simple:
The cardholder can signs in with Twitter to sync. The customer is then eligible to tweet current hashtag offers to receive savings. The savings is applied to the credit card. Done.
No coupons, printouts, or anything necessary.
For example:
Tweet “#AmexWholeFoods” hashtag and you’d get $20 back on your next trip to Whole Foods [with $75 or more purchase]. When you use your synced Amex, of course.
