DVCentury.com advertised 1 GB of DDR RAM for $78- I bought it- received a used 512mb module that did not even work right. I called and the owner "SAM" was very uncooperative. I will likely be taking him to court over this, and am now requesting a charge back from my credit card company. Fraudulent organization is not even BBB registered-I own a real computer store-with real bills, real problems and I don't have to rob people to make my living. This company needs to be shut down and that can only happen when people realize they are unscrupulous criminals that think they will never have to suffer any consequences for their shameful actions.
