Made the call yesteday, spoke to Timothy. Basically told him my wife wants us to switch to Dish as the package they have is $20/month cheaper and I could get RedZone channel instead. Currently, we are paying $60/month for our package plan. He said he could give me $20 off for 6 months. I told him I wanted it for 12 months because I didn't want to call back in 6 months just to extend the discount. He said that was fine, so $20 off for 12 months.
Then discussed the Sunday Ticket and asked what he could do to lower that as I still wanted to keep the ticket. He offered $20 off x 6 months for the ticket - told him I'd seen better discounts, and preferred a one-time credit instead. He came back and said he could do $125. I told him I'd seen people getting upwards of $250, and he countered that the best he could do was $150 one time credit. I told him I could probably swing that, but thought if that was the best he could do, I'd like him to throw in the to-go for free. He checked, and said that was fine. Ended up getting a $200 one-time credit off the bill.
In total, $440 in credits towards the bill. Not as huge as some of the deals in here, but to basically lower our monthly bill by $5-6 over the next year and get the Ticket was well worth it.
