We no longer offer discounts to non-profits unless you were explicitly told you would get one (via an email record).
Here is the basic reason (from Jason Fried):
“We don’t want to be one of those companies that has a ‘who you are determines how much we can charge you’ pricing model. We find those models unfair, dishonest, and flat out unappealing. The best pricing is clear, fair, public, consistent, and predictable.”
The only exception is if you are a K-12 public school teacher in Washington State you can use our premium or pro service for free.
