Expedia works hard at knocking down the barriers to travel, 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 location. How’s that for stress-free? The rental car company will also place a hold on your credit card for the security deposit. For some cheaper deals, you may have to pay at the time of booking. Take note of which payment options are available for the rental car you’re interested in.
