For the first time in years I didn't have Sunday Ticket last year. I called over the weekend to renew this year, but my call was originally about using a free upgrade to the wireless genie equipment. After getting that squared away, the call guy asked if I was interested in an HBO/Showtime package, and I said nah, I'd be more interested in Sunday Ticket. He said let me check what rate I can get you, and came back with $59 for 6 months -- but he offered a $30 credit applied for 12 months, and also threw in a random $3 monthly credit for 12 months, and a $5 credit for 6 months. So the Sunday Ticket package more than pays for itself over a 12-month cycle.
By upgrading my equipment I had to agree to a near 2-year deal, which I think was the reason I was offered the $30 credit. He started tacking on the others as I asked if there was anything else he could do.
