You buy an all-access membership for $180 and then you get a code you can send to another person and they get a 1 year free all access free membership. Essentially you can split with someone and pay $90 for a membership for one year. After that, it will renew for each person at $180 a year if you continue.
So far, I have watched Negreanu's class and I just started Ivey's. My son has watched some of the Steph Curry series (I can't imagine having a Michael Jordan MasterClass when I was a kid, lucky punk) and I've also started Aaron Franklin BBQ class. Good stuff so far, nothing earth shattering from the poker side of it. Negreanu's seems more put together and structured, Ivey's is more like 30 min segments where he just goes off on tangents but still awesome listening to him go through hands and what he was thinking.
