6 Ways to Save On Rental Cars

Avoid traveling during the busiest car rental season, which runs from June through August. Or, if you must travel during the summer, hunt down car rental coupons to get the best deal possible.

Big name car rental agencies may offer discounts, but that doesn't necessarily mean you're finding the lowest rates. Instead of going with familiar brands, look into smaller, independent agencies when renting. Since they have lower operating costs, their prices are often as much as 30% lower than mainstream companies.

Calling up the agency and asking about a current deal isn't the only way to find out about discounts. Sometimes the agent on the phone won't even know about all the specials they're running. Search online for coupon codes from third parties — many agencies give discount codes to partner organizations. Plus, you may be able to combine a discount code with a coupon code to double your savings.

Whatever you do, don't rent the car directly from the airport — off-site locations usually cost less. When you rent at the airport, you could pay 30% more than if you used the same exact agency elsewhere.

Book the lowest-cost car and then negotiate at the counter. Oftentimes, you'll be upgraded for free without having to say a word. Other times, simply asking for a nicer car could get you the upgrade without having to pay for it.

Several car rental companies give up to 20% off the total cost for customers who are willing to pay in advance. Just make sure to read about their cancellation policy, which may be more severe when you pre-pay.
