I would probably sign up again if Intuit had limited their increase to a fair amount based on CPI. 

I object, however to "added value" increase of over 60%.  They have the right to do so, but I have the right to change not only my software but have already targeted a competitor that can provide features at a substantially lower cost to the majority of my clients.  Wake up, Intuit, or you will drop your heavy market share.
