I signed up for HBO today on D*. I asked the front line CSR what deals they had and he offered me 50% off for 6 months ($18/2=$9 per month). I took the offer. I am setting up HBO Go on my Amazon Firestick and I noticed the listing online of devices for my HBO account. Does anyone know how many distinct streams I can employ. The HBO web site only states that "the number of simultaneous streams is limited for security reasons".
