I signed up for it via Roku, not hbomax.com. I'll probably go ask them sometime in the next few weeks after the Dish HBO initial flurry settles down.The deal to prepay for one year of HBO Max at a discounted rate ($150 totally ad-free, or $100 with ads in the non-HBO content) is available, as far as I know, only if you pay directly through the service by signing up at hbomax.com.
