Expedia works hard at making travel easier for everyone, that's why we offer the flexibility to reserve your ride 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 point. 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 be required to pay at the time of booking. Remember to take note of which payment options are available for the rental car you're interested in.
