If you've found your perfect set of wheels but don't want to pay upfront, Expedia has got your back. With our Book Now Pay Later option, you'll only pay in full on the day you collect your car in St. Marys. The rental company will also place a hold on your credit card for the amount of the security deposit. Cheaper rental offers may require you to pay upfront, but you'll see this at the time of booking. Whether you're after a zippy compact car or a sleek and sporty ride, Expedia is the gateway to your next exciting adventure.
