If you purchased a computer with a DVD drive or even just a stand-alone DVD play between 2003 and 2008, you may be eligible for part of a multi-million dollar settlement for price-fixing. Claimants are eligible for US$10 per device purchased during the period if they meet other eligibility requirements.
