Got email yesterday from where they stated that both Netflix & Wallyworl were sued by consumers for their agreement over DVD business.
WalMart agreed to give settlement amount of $27.25 million and if you claim for it by Feb 14'2012 you will receive the amount from it depending on how many claims they got if court agrees to pay.
