Expedia works hard at making travel easier for everyone, that’s why we give you the flexibility to reserve your rental car without paying upfront. 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. It’s as easy as that! The rental car company will also put a hold on your credit card for the security 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 you’re interested in.
