Expedia works hard at making travel easier for everyone, that's why we offer the flexibility to reserve your rental car without paying in advance. With our Book Now Pay Later option, you can simply present a valid credit card to pay in full at the pickup destination. How's that for easy? The rental car company will also put a hold on your credit card for the amount of the 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 the rental you're interested in.
