If you think finding the lowest airfare is tricky, try getting the best deal on a rental car. These days car rental rates change quickly. Here are some tips that should make for a smooth ride. First, try using a travel consolidator, such as Travelocity or Expedia, and compare prices among them. If you don’t go this route, don’t be afraid to ask the rental agency if it gives discounts for membership in AAA, AARP or a warehouse club like Costco or Sam’s Club. Most do. Watch for coupons or offers in travel magazines or at warehouse club check-out areas. Often you can couple a tidy discount with a free day’s rental or upgrade. Did you know it’s usually cheaper to rent from a non-airport location? You’ll pay taxes and some fees, but likely less than at the airport. Ask your hotel if there’s a nearby car rental agency. Or get the hotel’s street address and plug it into the rental company’s website. Some companies, such as Enterprise, will pick you up or drop you off – usually within a specified mileage radius — at no charge.Be sure to examine your personal vehicle liability and collision policies. Most cover rented cars as long as you’re behind the wheel. Some credit card companies also pay for damage as a premium card holder benefit. Call to confirm and, if so, use that specific card when you rent. For more tips, including hidden charges, local taxes and more, see the full article on Living on the Cheap, our sister site.
