Expedia is all about making travel accessible for everyone, that's why you can reserve your rental car without paying in advance. With our Book Now Pay Later option, you can just present a valid credit card to pay in full at the pickup location. It doesn't get easier than that! The car rental company will also put a hold on your credit card for the security deposit. For some cheaper deals, you may have to pay at the time of booking. Take note of which payment options are available for the rental you're interested in.
