Expedia is a big believer in making travel more accessible, that's why we offer the flexibility to reserve your rental car 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. How's that for easy? The car rental company will also place a hold on your credit card for the amount of the security deposit. For some cheaper deals online, you may have to pay at the time of booking. Remember to take note of which payment options are available for the rental you're interested in.
