It looks like Amazon is sending out notices to eBook purchasers to notify them that they are receiving credit in their Amazon account relating to the recently settled eBooks Antitrust Settlement case.
As you can see my windfall from this settlement is a whopping $0.73 cents.
Apparently the amount you will receive is based on the number of eBook purchases you made over the period covered by the settlement.
So what did you get in the settlement?
