Once in a while, I receive a mail asking me to claim my share of a class action lawsuit settlement.  Amount involved is usually tens of dollars to hundreds of dollars.  The problem is that I have to fill-out long forms and provide evidences.  I am certainly not inclined to waste my time filling out those forms nor search for whatever proof they are asking for and I suspect many feels the same way or are as lazy/focused as I am.  So I am wondering where all the unclaimed millions are going to.

If they have enough information about me to ask me to file a claim, why can't they just send me my share of the claim?  For example, I have bought and registered many Windows and Office products so all the information and proof should be in Microsoft databases.  Why can't they make use of it instead of burdening me with chores to claim a lousy hundred bucks?  If that is impossible, why not use the money to reduce price on Microsoft products across the board?

I don't particularly care where the difficulties are other than that they are passing their difficulties to me.
