Filling up you gas tank could now be costing you $100! Since for many of us changing to a cheaper car is not possible, let's try to save some money on our car insurance.

If you have become a car-pooler or a regular user of mass transit with the hike in gas prices, let your insurer know. Some insurance companies provide low mileage discounts when cars sit in garages or driveways all week long. But, be prepared to prove the change in your driving patters.

If your insurance company doesn't offer this discount, consider switching companies. But don't wait until your current policy expires. Start looking now!

There are insurance companies that offer early shoppers a discount, some as much as 12%. An early shopper is often viewed as a savvy consumer. Wait until your old policy is coming up for renewal and you might be perceived as someone in trouble with their insurer.

So got for it! NOW!
