For what it's worth, I have Direct TV Extra and was able to obtain the Sports Pak for 13.99 per month with a 5.00 discount for 3 months. I was told I could cancel at anytime. I'm watching LHN as I type.
Just two weeks ago another Direct tv rep told me I had to upgrade to the Premier package. She was obviously wrong.
I'd recommend a call to customer service and see what they can provide in your specific area based on your current Direct tv package.
I thought I'd have to head for a bar. Glad I called !!!
