Making money is now as simple as a tweet.

American Express has launched a program that gives customers discounts for tweets, according to Mashable.

Customers go to a website where they sync their cards to their Twitter accounts. Whenever they tweet special offer tags in the messages, customers receive savings loaded onto their cards without the need of a coupon.

When customers go to buy items at participating merchants, the savings are automatically deducted.

Best Buy, McDonald’s, Whole Foods Market and Zappos have all signed on to the new programs.

The trade-off of discounts for the customers and free marketing for American Express is the idea behind the program.

This isn’t the first time AmEx has used social networks. The company launched a “Link, Like, Love” campaign on Facebook last July that gave users offers if customers liked participating merchants.

AmEx also offered deals through Foursquare, a location-based social network.
