@boomerang,
I'm a member. I don't remember what the annual dues are any more; I have them deducted automatically from my bank account. They're certainly not exhorbitant, less than being a National Geographic Society member, I believe. Is it worth it? Well, you do get some discounts with your AARP card at car rental places, for example, and other venues as well. But I really believe in supporting AARP because they're the lobbying arm for senior-friendly legislation in Washington, DC.
