Getting a car insurance quote online is a great way to get a discount on your car insurance.
Most car insurance companies offer an online discount for car insurance of around 10-15% off.
The reason they offer online car insurance discounts is because you are getting the quote yourself from the system and are not having to speak to a sales person. In effect you are removing the sales person.
Needing less car insurance sales people saves the car insurance company money in wages, also they will not need to pay an employee a sales bonus for making the car insurance sale which again saves the car insurance company money.
