You can buy life insurance online from websites that have quote engines. The ones that offer instant quotes allow you to input your age, gender, height, weight, whether you smoke, and whether you have other risk factors (dangerous hobbies, health conditions, felonies, etc). Then the best quotes from several companies show up, and you can pick the one for which you wish to apply.
The more detailed the quote engine, the more accurate your quote will be. But it still is helpful to talk to or correspond by email with someone at that online agency to be sure "all the bases have been covered" and you are applying with the best quote for which you qualify.
Buying life insurance online is as easy as hitting Google, Bing or Yahoo. There is no shortage of buying life insurance online. My question is why buy online? You still may not find the best price for the product you are looking for. I highly recommend contacting an experienced independent broker you are comfortable with. The cost for service is free to you the consumer. Life insurance companies do not sell it any cheaper online than they do through a broker. This way you get expert advise for free.
