Expedia believes in knocking down the barriers to travel, that's why you can reserve your ride without paying upfront. With our Book Now Pay Later option, you can just present a valid credit card to pay in full at the pickup location. It's that easy! The car rental company will also put a hold on your credit card for the security deposit. For some cheaper deals online, you may be required to pay at the time of booking. Take note of which payment options are available for your choice of rental car.
