Does it have a keyboard drawer? And does it have a storage drawer?
It does have a keyboard drawer that tucks right underneath but there is no drawer.  
The chair looks a little tattered? What kind of shape is it in? Also, does the desk come assembled or will I need to put it together?
Both the desk and the chair are in good condition.  There is no major damage anywhere.  It is together at the moment and I have a truck if you need me to deliver it.
That sounds good. Can you negotiate on the price. I was kind of hoping to get something more around 40. Can you do that?
I will do that.
