Heads up, awardtrail readers! Check your Citi Offers account ASAP because a targeted deal is back, potentially saving you some serious cash on your AT&T wireless bill. Select Citi cardholders are seeing an offer for $40 back when they spend $65 or more on a qualifying AT&T wireless plan. The current iteration of the deal is valid until February 28, 2026. Why is this important? Well, if you're already an AT&T customer, this is essentially free money for something you're already paying for! Just make sure you activate the offer in your Citi account and pay directly with your enrolled card. While the fine print mentions it's for new customers, past deals have worked for existing ones too, making it worth a shot. Just a heads up, AT&T Prepaid plans are excluded.
