Just called and got it reduced to 6 payments of $29.99 ($180).
That's down from the $299 he told me it was at when I called. All I said is that I wanted to cancel Sunday Ticket after 15 years because the price was too outrageous.
Call took all of 5 mins, and he said the price was as low as he was allowed to go. (True or not I dunno, but $120 off...I'll take it.)
