Nice job!
I'll piggyback on this thread, since this doesn't warrant its own: Our one-year "new customer" special with Comcast ran out, which meant our monthly bill would go from $20 to $40. Usually, if you call and tell them you want to cancel, they'll offer to keep you on the same plan for another year. Two years ago, for some reason, they refused, so we switched providers for a year until we could qualify as a new customer again.
This time, they offered to keep us on the new customer discount for another year. I saved $240 for about half an hour's work.
