6 Year customer Moving - Time to Call Retention?

[NextLevel]

Moving from Chicago to Raleigh, N.C. time Warner Cable (ugh). Could use them for internet only, but I'd prefer a bundle (saves some money) for internet + cable.

Question(s):

(1) I've been a DTV cust for 6 years. What kinds of discounts, specials, promo's, etc, can I get by calling retention?
(2) Is there a comparison website/feature/application that I can use to model the pricing and offerings of TWC versus DTV?

Thanks all.
