This is almost exactly what my experience has been with DirecTV over the past several years, and, like you, I also expect that being able to call in, threaten to cancel, and then get a great deal will not be possible for much longer. I was able to do this successfully about 3 months ago (getting my monthly bill down to $90 for TV & HSI combined), but I'd guess when my monthly discounts and credits run out early next year, they won't be willing to offer enough new ones to retain me as a customer. DirecTV is losing subscribers at such a huge rate that it wouldn't surprise me at all if AT&T were to announce that they're winding the service down completely within the next couple years.
