Why not just use HBO NOW if you have HBO? HBO GO was set up so you could cut the cord. After having HBO GO for 3 years they want $100 from me to register my HBO GO so I can use the HBO GO app. Is HBO going to charge us $100 this year $200 next year and so on? Game of Thrones maybe a great show but is it worth $280? I can buy the 4K disk for $50 and save $230. So much for being a loyal costumer.
