Expedia is passionate about making travel easy and accessible, that's why we give you the flexibility to reserve your car without paying in advance. With our Book Now Pay Later option, you can simply hand over a valid credit card to pay in full at the pickup destination. How's that for stress-free? The rental car company will also place a hold on your credit card for the amount of the security deposit. For some cheaper online deals, you may have to pay at the time of booking. Remember to take note of which payment options are available for your choice of rental car.
