Expedia is a big believer in making travel easy and accessible, that's why we offer the flexibility to reserve your wheels without paying in advance. With our Book Now Pay Later option, you can simply hand over a valid credit card to pay in full at the pickup location. How's that for easy? The car rental company will also put a hold on your credit card for the security deposit. For some cheaper deals, you may be required to pay at the time of booking. Be sure to take note of which payment options are available for your choice of rental car.
