Expedia is a firm believer in knocking down the barriers to travel, that's why we offer the flexibility to reserve your rental car without paying in advance. With our Book Now Pay Later option, you can just hand over a valid credit card to pay the cost in full at the pickup spot. It's as easy as that! The car rental company will also put 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. Take note of which payment options are available for the rental car you're interested in.
