How to find car-rental discounts
Finding a bargain when renting a car has become more and more difficult. Booking engine autoslash.com posts coupon codes from metasearches and will also track your bookings after they are made in case better offers become available. When we searched the site, we found coupons for free weekend days at National (877/222-9058; nationalcar.com) and for 25 percent off weekly rentals at Budget (800/ 527-0700; budget.com).
