I just found a new platform Zeffy. 

We will be using it as an option for members to donate money. I also used it for our Blooming Bags Bingo fundraiser to sell tickets and very soon for people to pre order popcorn for the Iowa vs Iowa State fundraiser. 

I know below sounds like a commercial, but it is great! 
 Zeffy is the only 100% free fundraising software for nonprofits - they even cover transactions fees. It’s incredibly easy to use, offers a full suite of fundraising tools, and they provide unlimited customer support—all for free.

 Use our referral link to sign up here: https://www.zeffy.com/en-US/referral?referredByOrganizationId=a1932a2c-51f3-45a4-ae85-8b32b32220d4

Totally loving zeffy!
