Movikx had a great thread about this topic a few weeks ago and even PM'd me some info on alternatives to DirecTV (ala getting Vikings/NFL games).
I called a couple times and they reduced my bill for Sunday Ticket by $60. It's now $240. When I signed up last year, I agreed to a 2 year price lock guarantee of roughly $80 a month. Somehow, I recently got my bill and it was $130. I called and they said that the NFL Sunday Ticket promotion being free is only for new customers.
"But what about the price lock guarantee?"
"That's only for your regular channels."
"The ones I don't watch?"
"... yeah."
I'm quickly reminded that you're not a customer to these companies. You're a number and you're shot through some customer service person's flow chart. And now the onus is on me to find a way to get out of my 2 year price lock guarantee. I'm still on the hook for another year I was told for cancellation fees, etc. Fuckers.
