New Computer

I am online today searching for desktops. My husband has finally come to the conclusion that he needs one. I have known this for a while, but I figure there was no point in looking around until he finally decided he needed a new one. Now that he has, he wants me to find him one at a good deal and fairly quick. I know his work depends upon it, but there is only so much time I have to look. Why is it that some people think just because you sit at a computer and desk to work all day that we have all this time to look around online?
