Expedia is a big believer in knocking down the barriers to travel, that's why we give you the flexibility to reserve your wheels without paying upfront. With our Book Now Pay Later option, you can just hand over a valid credit card to pay the cost in full at the pickup destination. How's that for easy? 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 be required to pay at the time of booking. Be sure to take note of which payment options are available for your choice of rental car.
