Update - called back today because i got charged the first installment for ST on my latest bill (even thought i'd been assured after the last calll i wouldn't be charged). Used that angle to ask to talk to a cancellations. And then i heard the magic words: "What can i do to make you a happy Directv customer today." I was honest. I told them the only reason i signed up for directv was ST. He said the best they could do was half off...so $112.50 for ST. I then proceeded to press my luck and asked for the ST Max at the ST discount price which he said he couldn't do but did offer me the same hald off deal at $150. Then i mentioned that i had friends (you guys) that were getting ST Max for free. He said that was impossible and the only free offers were for brand new customers. He hemmed and hawed but eventually offered me an additional $20 off the Max. At that point, I had to bite.
I'm more than happy to pay $130 for ST Max - that works out to less than $8 a week for 17 weeks of football, including RedZone, mobile/tablet/pc, and short cuts (replay games in 30 minutes). The call took 39 minutes. Thank you to everyone here for their stories and advice.
