This final note today, which speaks volumes about:

1. Health care pricing in this country
2. Why the daily discount site Groupon is in such a bad place.

This offer popped up today in a friend of mine's email inbox. An MRI, including a carotid artery scan, brain aneurysm scan, or both, with 3-D imaging and private consultation -- starting at just $39.

The brain scan package is worth $900; so with the Groupon, your savings are 96 percent.

Or...it's just crazy.

The amazing thing? More than 140 have been purchased.
