Expedia is a big believer in making travel easy and accessible, that's why we offer the flexibility to reserve your wheels without paying in advance. 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 stress-free? The car rental 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. Be sure to take note of which payment options are available for the vehicle you're interested in.
