Round-the-clock roadside assistance comes in handy when you pop a tire, run out of gas, or drain your battery while powering a disco ball in the supermarket parking lot. Keep parties moving with today's Groupon: for $37, you get a one-year Basic membership to AAA (a $73 value).

Founded more than a century ago to lobby for safer roadsters and fair street laws, AAA today keeps more than 50 million drivers cruising smoothly with vehicular aid available at all hours. Basic members find solace in AAA's 24/7 roadside assistance, which includes free towing for up to 4 miles and delivery of fresh fuel for drained gas tanks or jet packs. Mechanical mavens also juice up exhausted batteries and coax open accidentally locked doors. Slashed prices on SiriusXM radios and LensCrafters specs complement the discounts AAA members receive at more than 160,000 other retailers. Full-service travel agencies grant drivers bargains on getaways, including airfare, rental cars, and more. Though not included in this Groupon, customers can keep all of their transportation needs in the AAA family with access to full-coverage insurance to help protect horseless chariots from potholes filled with medieval maces.
