Expedia enjoys making travel easy and accessible, that's why we give you the flexibility to reserve your ride without paying upfront. With our Book Now Pay Later option, you can simply hand over a valid credit card to pay in full at the pickup spot. 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 deals, you may be required to pay at the time of booking. Take note of which payment options are available for the rental car you're interested in.
