Expedia is a big believer in knocking down the barriers to travel, that's why you can reserve your wheels 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 rental car company will also place a hold on your credit card for 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 rental car you're interested in.
