You are going to lose customers. I don't ever recall this being comunicated, but regardless it's pretty bad. I know there is a reason you do not allow cancelling subscriptions through your website.
When i started my personal pro subscription it was $99. Then in one year it jumped from $99 to $249. Shocking but I hung in there. Then I get a bill this year and it jumped another $100! Who is running this company? Did you hire John Stumpf from Wells fargo?
What is the reasoning behind the drastic price increase?
I used Pro for emergencies Few times a year and didnt mind the $249. But now over 800?!?! I would have never agreed to this increase.
