Just for fun, I went and looked at some rates with BCBS of GA (my insurance company and one, if not the, most expensive and best ones out there).
The parameters were a 42 year old female, her 42 year old husband, their 21 year old female student daughter and a 14 year old son.
The HIGHEST rate for this family was $528 a month. $500 deductible, $20 copays. They are all non-smokers, BTW
