Expedia is a big believer in knocking down the barriers to travel, that's why we give you the flexibility to reserve your rental car without paying in advance. With our Book Now Pay Later option, you can simply present a valid credit card to pay in full at the pickup spot. It's as easy as that! The car rental company will also place a hold on your credit card for the security deposit. For some cheaper deals online, you may have to pay at the time of booking. Be sure to take note of which payment options are available for the vehicle you're interested in.
