I would really do some careful investigation before going with any service endorsed by AARP. They used to push People PC for dial up internet. There were a lot of complaints about it on the internet and that AARP wouldn't give any relief.
The cell phone service, Consumer Cellular, that AARP pushes because it isn't a prepaid plan is actually more expensive to use than many prepaid plans. AARP touts that all you need is a credit card. Big deal. I have Virgin Mobile (which works fine where I live and most places I go). I have to top up only when my balance runs out or a minimum of $20 every three months. I have my account set up to automatically top up $20 every three months or if my balance drops below $5 (the three month clock starts after each top up). The money is taken from my debit card account. I pay $0.18/minute. Last time I checked, it was $0.20/minute for new subscribers. Consumer Cellular, at the time I checked and Virgin Mobile was $0.20/minute, was $0.25.
AARP's medical insurance plans are through United Health Care, one of the poorest health insurance companies around.
Again, I would very carefully investigate any auto or RV insurance plans offered by AARP.
AARP successfully lobbied in AZ several years ago against a bill that would force medical insurance companies to allow patients to choose their own doctors even if they are out of network, claiming it would increase costs. Although I seriously doubted that, even if it did, the increased quality of medical care would have been worth it. The only reason I maintain my AARP membership anymore is for motel discounts (the savings on one stay usually pays for the annual dues).
