Expedia works hard at making travel easy and 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 simply 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 be required to pay at the time of booking. Take note of which payment options are available for the vehicle you’re interested in.
