Car rental prices vary depending on the season, demand and availability - similar to the airfare prices. The sooner you will make the reservation, the better price you will get- at least in most cases.
This is why we recommend our customers to make a reservation for a rental car as soon as you know your flight dates and time as well as you have chosen the hotel- possibly exactly the location of the hotel will impact the driving route.
If at the time of making a reservation your finances are limited, we advise to choose to pay for the service at the time of receiving the rental vehicle. If your plans change, you will be able to change the reservation data or even cancel the reservation free of charge. Your benefit- fixed price and security that rental car will be available for you. No risk at all!
If your flight dates are known and your travel is already planned, prepaid offer will let you save and pay less for the received service. The choice is yours!
