Right now when I log into mydish there is an HBO Max Offer for me. Also available under Premium. $10 for Cinemax, $15 for HBO Max. The details of the offer says "Get six channels of HBO and all of the streaming content that HBO MAX has to offer for just $12 per month for 12 months." It doesn't look like Cinemax and HBO are together though, unless Cinemax is part of HBO Max?
I am only up because of the severe thunderstorms working their way through the Chicago area. I can't get signal on my satellite dish to see if they are in my EPG or not.
