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 simply present a valid credit card to pay the cost in full at the pickup destination. How’s that for stress-free? The car rental company will also put 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 the vehicle you’re interested in.
