Most of our customers began with us servicing their computer(s).   Unaware that we do sell computers and related equipment, they have often asked us to provide them with such items.  They desire to have "one place to call" when they do have computer and printer needs.  This removes the inevitable finger pointing when a compatibility question arises.  Passing the buck is impossible when you are talking to the ones who make the decisions.  Our customers have found this to be a big plus as compared to other service companies.  Who knows your equipment better than your service provider?
