There was a feature on working lunch regarding dead pixels and buying on line. Under the distance selling regulations, you can cancel the contract with your suppler without giving any reason within 7 working days. This means that you could buy a lcd PJ online and any dead pixels, send it back under the regulations. The advice was not to argue about faulty goods etc, but just to send back because you no longer want the item under the distance trading regulations. Good feature and well legal.
