Dish customers - Get premium movie channels for 50% for 6 months
I just found out that DISH Network is having a promotion at least until the end of this month where you can get HBO, Showtime, Cinemax, and Starz for 50% off.
I couldn't find this online anywhere so you have to call to get it.
HBO - $9 (normally $18)
Cinemax, Showtime, and Starz - $6.50 each (Normally $13 each).
