Expedia loves 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 destination. How's that for stress-free? The rental car 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. Be sure to take note of which payment options are available for your choice of rental car.
