i dont think anything is negotiable with bloomberg unless you are a JPMorgan (and i'm not even sure they have a lot of negotiating room).
only crap services try and lock you in from the start cause they know you will cancel after the hype is over.

I wonder if they give discounts to educational institutions? Most s/w, medicals, engineering... give discounts to students.
