Your Twitter addiction might save you some money starting Tuesday.

The company has launched Twitter Offers, which lets marketers run promotions that you can redeem via your credit card. If a Twitter Offer pops up in your timeline, now you can add the Offer to your credit card or debit card. When you click to buy the item, the discount will be applied, though the cash back won't show up for a few days.

As with Twitter's Buy button, to redeem the offer, users have to click on it. Then they'll be directed to a landing page where they can enter their credit- or debit card info.

Once you enter your card information, Twitter has it on hand so you can redeem future offers without that hassle. (Having your data also helps Twitter push its "Buy" button.)

For advertisers, Twitter Offers presents a way to track ROI for Twitter-based promotions. If 50 people redeem an Offer, for instance, they can work out how much they spent for each redemption.

The company says it is planning to work with a "handful" of unnamed brands for Twitter Offers this holiday season.
