Time it takes: 7 minutes
Simply raising your deductible can save you up to 30%. With an old car, drop your collision and comprehensive coverage when the car is worth less than 10 times what you pay for the insurance. Or shop for a lower premium at insweb.com, an easy-to-navigate comparison site. You'll be guided through five screens of information such as driving history, car make and model. A few minutes later the site will give you the lowest quote from its database (which doesn't include all the biggest insurers). Agents will also e-mail or call you with quotes from other insurers.
