Hi there, sorry to hear about the confusion. All AARP member benefits can be accessed on the AARP Member Benefits page, which provides a full list of current providers who offer deals, benefits & discounts to AARP Members: https://www.aarp.org/MemberBenefits
When viewing the page, click on the name of the benefit (like AT&T under Technology & Wireless, in this case) to see a description of the benefit, and click "Learn More" to head over to the provider's website to get started with using the benefit and/or discount. When clicking on AT&T on the AARP website, the description explains that AARP members can save up to $10 per line per month on the AT&T Unlimited Premium℠ plan, plus receive up to $45 in waived activation and upgrade fees. I hope this information is helpful and thank you for your feedback.
