CHARLOTTE, N.C. - Barry Miller figured he was saving $100 a month when he scaled back his disability insurance. After all, he was healthy.

"It just looked like the policy was too expensive," said Miller, who was paying for his own disability insurance carried over from a previous job. "Sometimes you don't know what will happen."

What happened was this: In January, he was diagnosed with Bell's palsy, a condition that causes facial paralysis. Now, at 61, he has left his job as a sales manager for a girls' accessories company, and the Ridgewood, N.J., resident pays $3,000 a month for disability insurance.

This is the summer of the new frugality. Americans everywhere are clipping coupons, searching for freebies, and finding creative ways to save money. Saving money is chic; another way to impress the neighbors.

But others are making far tougher choices that threaten to cost them far more than they save.

Reducing insurance coverage, whether it is a consumer or a small business making the cuts, does bring instant cost savings. But it is proving to be problematic for some people, leaving homes and businesses underinsured and their owners' facing huge monetary losses should disaster or illness strike.

"The economy is prompting a lot of people to reassess or reevaluate everything everywhere, and they are looking to make sure they are getting the most for their money," said Mark Gibson, assistant vice president of advertising for State Farm Insurance Cos. "Our industry is no different."

That creates something of a buyers' market. Many consumers are shopping around for the best price.

After receiving a rate increase notice last year for insurance polices on two automobiles and two homes, Justin Gregonis decided to leave his current insurance provider and go with a cheaper company. Gregonis, of Phoenix, said he was able to get the same amount of coverage without changing his deductibles for a savings of about $1,200 a year.

"I was willing to go with whomever was going to get me the best rate and have the best coverages," he said. "Insurance in itself is just basically like playing the lottery. It's just a gamble, but you have to have it."

Consumers' willingness to abandon their insurers is making some companies work with customers to try to retain them.

Companies such as Allstate Corp. and Travelers Cos. are introducing new discounts and lower-priced products. But consumers need to be careful about discounts, for example, when carriers offer lower prices to customers who buy both homeowners and auto policies.

An Insurance Resource Council survey questioned 1,000 adult consumers by telephone in December and found that 28 percent with at least one vehicle shopped for lower rates on their auto insurance, while 9 percent said they had canceled or decided not to renew their auto coverage.

Five percent of homeowners surveyed said they had canceled or not renewed their homeowners' insurance, as did 14 percent of renters.

"We expect consumers to be taking a lot of steps to reduce costs," said David Corum, vice president of the Insurance Resource Council, an industry-supported research organization. "People are willing to take on more risk in tough economic times to save money, but when they do that, the outcome can be catastrophic."

There are certain policies that consumers and businesses absolutely must have - auto insurance, for example, or homeowners' insurance for people with mortgages. But many consumers are sliding by without discretionary coverage such as life insurance or even health insurance. And small businesses may not be buying enough insurance to cover their losses, or to guarantee they will stay in business should disaster strike.

The less coverage consumers and companies have, the more risk they take on. It is a hard choice, but one many consumers feel they have to make.
