Expedia believes in making travel easy and accessible, that's why we offer the flexibility to reserve your car without paying upfront. With our Book Now Pay Later option, you can simply hand over a valid credit card to pay the cost in full at the pickup spot. How's that for easy? The rental car company will also place 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. Remember to take note of which payment options are available for the vehicle you're interested in.
