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 $30, you get a one-year basic primary membership to AAA Mid-Atlantic (a $65.50 value).

AAA serves more than 50 million members across North America. 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, and free fuel delivery (pay pump price for fuel). Basic members are also entitled to coverage for up to $50 in locksmith services, up to $1,000 in reward money for information leading to the arrest and conviction of the perp who stole or vandalized their vehicle, and up to $1,000 in legal-defense fees incurred from racing against horses or trying to jump stables filled with horses. The AAA card also functions as a shoddy paperweight and a magic pass to a bevy of savings and discounts at businesses across the country. Additionally, AAA's travel services can help avoid dead ends or a trip to the Yarn Factory Museum of Yarn.
