Even if you have a season ticket the RTV unlimited package is a better option. Especially when there are at least 3 or 4 away games per month. It's nice that even when you are at the game yourself your friends and family can actually watch the home games.I don't have the full Rangers TV (I've got RTV plus - no point in full package as have a season ticket) package plus an extra £9.99 for the away ties.
However, I wouldn't pay to watch football on TV unless it was Rangers.
Also, God willing when we get there, I will only be watching Rangers group stage games in the pubs that paid for RTV in the qualifying rounds.
