How to get AARP promo code for discount on Thriftbooks

I am an AARP member wanting to use the AARP discount available on ThriftBooks. Per ThriftBooks blog November 2025, I would verify membership by keying AARP member number in given link and receive a promo discount code to use at checkout. The link did not provide a way to verify membership.

 

I contacted ThriftBooks customer service who suggested:

“I'd recommend reaching out to AARP directly to inquire about their partnership with ThriftBooks and how to obtain your member discount code. They should be able to provide you with a code that you can apply at checkout. “

 

Can you help please?
