Here's a query I got from an accounting colleague of mine...any comments would be appreicated.

Hi Dan.
I have a business law question.  I'm teaching students about internet pricing schemes.  It appears that businesses are using the Internet to practice some segmented pricing - offering different customers different prices.  It seems to me that the Robinson Patman act (which I vaguely recall from my business law courses) said that you could only charge different prices if you could show that there were also different costs - for instance, lower distribution costs.  Is this true?  Are there any regulations regarding pricing these days?  Is anyone concerned about Internet pricing?
