Whenever I need one I always want to get the best deals on a car rental. It takes a little research but it is worth it. You will save money.
CHOOSE A CAR TYPE - You will first need to choose which type of car you want to rent. If you do not have the car type you will not be able to adequately compare prices. You do not need to pick the exact type of car just pick from the groups that the car rentals offer such as compact, midsize, mini vans etc.
GET QUOTES - Compare quotes from different car rental web sites such as Avis, Budget, Thrifty, etc. Once you have a good idea of the price range for your car type you can dig for a deeper discount or deal. Make sure you find out the total with all fees and costs included so that you can accurately compare. I would recommend the insurance they offer for the car. Even if your insurance covers you, it is much easier to go with their insurance because if there is an accident, you can will not have to do anything if you have purchased the car rental agency insurance.
CHECK PRICELINE - Next you should check with priceline.com. Take the lowest price that you found with your quotes from car rental companies and request a quote from priceline. I would try $5-10 less per day at priceline. They should give you a total with all the fees. You cannot go just by the per day rate because priceline.com seems to come up with many other fees. You need to check the total. These are important steps in how to get the best deals or a discount on a car rental.
FURTHER DEALS - If you are still not satisfied that you have the lowest price, type "discount car rental for (insert city here)" in your search engine. You may be able to find an independent car rental agency that will give you a better deal. A little research and you will figure out how to get the best deals or a discount on a car rental.
