Buzzsprout offers what they call an affiliate program that offers you and the person you send to Buzzsprout a $20 Amazon.com gift card when they upgrade to one of the paid plans.
I consider this more of a “refer-a-friend” deal than a true affiliate program. It acts more like a “reward” than a commission.
That being said, if you are into the software, go gather those gift cards. They can add up quickly! And who doesn’t love Amazon?
