Same as above. We do usually order coding books from them, but they call constantly. I did have to put in  a complaint to their sales department. The thing that makes me upset is, is that when someone answers the phone here in the office, they ask for me but fail to identify themselves. When the girls ask if there's something they can help with, they refuse to speak to them and just say that they'll call back--even though we have told them numerous times that we aren't interested in buying anything else at this time and once we ARE, WE will call THEM.
