Expedia believes in making travel accessible for everyone, that's why you can reserve your ride without paying upfront. With our Book Now Pay Later option, you can just hand over a valid credit card to pay in full at the pickup destination. 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 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.
