Ask HN: SaaS Discounts for Non-Profits?

I've just become a Girl Scout Co-Leader for my daughter's troop. I was an Eagle Scout growing up so the landscape / environment is pretty different. In talking with other Troop Leaders there are some that are making use of webapps / social media and those that aren't. I'm personally using Trello, Google Drive, and am working with the girls to standup a little Wordpress blog on my AWS account. Are there any SaaS companies that offer special pricing for charities / Girl Scouts / Boy Scouts / Stem Scouts / etc? Does anyone have any recommendations on where to find out more information rather than contacting each company directly?
