This interview is what sold me on Mixergy. If you have a SaaS app, the part about pricing plans is the most important 45 seconds of your day today.
I listen to Mixergy as a podcast (not live) and usually end up deleting 19 out of 20 after I listen to them. This interview with Kevin Hale is one of the very first ones I decided to keep.
I liked the Thank You card idea Kevin talked about and might have to start trying that myself.
