Expedia makes travel accessible for everyone, so yes, you can! Choose your Downtown St. Louis rental vehicle with our Book Now Pay Later option and pay nothing until it’s time to pick up your ride. While you’re grabbing the keys, the car rental company will also put a hold on your credit card for the amount of the security deposit. Rather get your payment settled first thing? It’s easy to settle the bill at the time of reservation too. No matter where the road takes you, Expedia’s quality rental cars give the freedom to create your own itinerary.
