Is it best to go with a provider who can offer a bundle of phone, internet, and TV services?

In general, it is best to go with a service provider that can offer you a bundle of services because you can usually get a promotional rate. The problem is that after an extended period of time, the promotional rate may no longer be offered and the provider may try to increase the rate. At that time, it may prove more cost effective to go with multiple service providers to get the most competitive rates available for your service area.
