Expedia believes in making travel easier for everyone, that's why you can reserve your ride without paying upfront. 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 stress-free? The car rental company will also put a hold on your credit card for the amount of the deposit. For some cheaper deals, you may have 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.
