Called 'Twitter Offers', the new feature will appear on your timeline as promotional tweets posted by certain retailers.

Currently available only for US users, 'Twitter Offers' will incorporate a 'handful of brands' for testing during the holiday season.

"As we continue to learn and improve based on the experience of our advertisers and users, we will make this feature available for more advertisers," Twitter said in a statement.

The retailers' tweets will announce some money-back savings in a special deal.

If you are interested, you can click on a button called 'Get offer'.

The offer is then added to your credit or debit card.To redeem the offer, you then use your card at the retailer's store.
