If your Summer travel involves renting a car, here are some ways to avoid unnecessary fees: by adding insurance from the rental company you can add up to 60% to the bill! Most car owners are already covered under their own auto insurance or credit card. Check before you add. Upon returning the rental car, take photos of it and the rental agreement stating it was brought back damage-free. This way, if the next renter claims a damage was already there, you have proof. And lastly, do not agree to prepay for gas. Most times, depending on how long you have the car, renters don’t use a full tank of gas so in these cases you will be paying for gas you did not use. The best bet is to fill up before you return the car and keep the receipt to prove it in case you are charged for refueling.
