Expedia works hard at knocking down the barriers to travel, that's why you can reserve your ride without paying in advance. With our Book Now Pay Later option, you can just present a valid credit card to pay the cost in full at the pickup location. How's that for easy? The car rental company will also place a hold on your credit card for the amount of the 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 rental car you're interested in.
