Here's your options in the United States (correct me if I miss some):
- Subscribe to Directv, pray and hope they'll give you a reduced rate (a yearly game that I used to play, but got sick to death of). Once it hit the 300 dollar price point, I stopped paying. Initially they gave it to me free to hold me as a customer, but that stopped last year. Now they'll happily give long-time subscribers free Redzone Channel, which they just did for me again today. Just call a CSR and request it.
- Pay full price to Sony to get it on Playstation 3. Bear in mind that the service you're paying for is the stream that Directv provides to consumers of its mobile package. In other words, it's horrible on a big screen. Crappy audio, crappy video, all at full price. But hey, no Directv required, and you dont even need to lie about not being able to subscribe to Directv. As far as I can tell, there are no deals whatsoever anymore on this service.
- Buy this year's Madden 25 Anniversary edition for 99 dollars for Xbox 360 or PS3. Each copy ships with a code that allows the consumer a season-long license to the mobile-only version of Sunday Ticket. In other words, good for your PC, tablet, or Phone. It includes every channel available to people that buy the PS3 option. In essence you're paying 40 dollars for this (60 for the game, which you could immediately turn around and sell as new if you felt like it)
Personally I'm going with Redzone on Directv, and also getting Madden to have access to any game not available to me Over the Air.
If there's any deals running through Directv or otherwise, feel free to post them here to help others out.
