Prices for loaner vehicles fluctuate constantly, but not many travelers take the time to recheck rates after booking, even though there’s no fee to cancel or change a reservation with any major car-rental company. To make this task easier, book with AutoSlash.com, a site that continues to check prices (on both domestic and foreign reservations) until your pickup date. If it finds a lower rate, you are automatically rebooked for free, and the new confirmation details are sent to your in-box. For a recent weeklong car rental in Los Angeles that originally cost $227, AutoSlash rebooked the reservation twice, reducing the price by $19. It also offered a free upgrade from a compact to a midsize car.
