If considering Sunrocket then wait for the $99 per year offer (2 year contract). They almost always run this discount during holidays. They might have run one during Easter. Mothers' day, Fathers' day, Memorial/Labor day are included in their campaign.
www.slickdeals.net announces these as they come up.
I was ready to go with them but went with the Cablevision internet/Phone/TV package and I'm very happy.
