We buy almost all our computers from there and have always found a good deal. They are returns and refurbished, but they look and function just like new and come with the same warranty as a new one. I have a refurbished laptop and the only way you can tell it's a refurb is the sticker on the bottom.

DH bought a 'scratch & dent' desktop and when it arrived there was no scratches or dents to be found -- looks just like new.
