Take lots of car trips? Join AAA

If you need emergency road repair, or even help with a dead battery in your own driveway, it pays to belong to AAA (American Automobile Association, www.aaa.com). In addition to roadside assistance, the association has other great services, such as discounts on rental cars and hotel rooms. Memorize the number for long trips: 800/AAA–HELP (800/222-4357).
