How can I save money without sacrificing coverage of insurance ?

If You are buying insurance with coverage, its mean you are saving your money because at the time of brokage or any kind of loss you have to pay only a specific deductible amount, thats it. 

When you buy insurance you should sacrifice a small amount of money that is insurance premium to avoid sacrificing a large amount of money upon loss occurrence .

However the insurance company my facilitate the premium payment and allow you an installment payment for the annual premium
