Even the most careful drivers can be waylaid by tire trouble, an overheated engine, or deer foraging for hamburger wrappers. Prepare for on-the-road mishaps with today's Groupon: for $35, you get a one-year classic primary membership from AAA (a $71 value).

The automotive club AAA serves more than 52 million members nationwide. Although membership offers myriad benefits, AAAers benefit most from the peace of mind provided by the comprehensive roadside assistance program. On-site mechanical services are available almost anywhere in the United States for common car troubles such as flat tires, dead or murdered batteries, and creamed-corn-related engine troubles. Benefit highlights include free installation of spare tires, free battery boosts, free towing to the nearest responding facility (or up to five miles to any destination), and free fuel delivery (pay pump price for fuel). Classic members are also entitled to coverage for up to $50 in locksmith services.

All AAA members are eligible to receive discounted maps, travel books, and domestic guides. The AAA card also functions as a shoddy paperweight and a magic pass to a bevy of savings and discounts at thousands of businesses across the country. Additionally, AAA's travel services can help you avoid a trip to the Yarn Factory Museum of Yarn.
