Research the channels for which you are considering a subscription. Due to extra fees, it is a good idea to be certain about how much you will pay and what you will be getting in return.
Visit the website of your cable provider and look for any promotional deals that may be running. Cable companies will often offer premium channels at a temporarily discounted rate as a way to boost subscriptions.
Call your cable company's customer support line. This phone number should be located on their website under "Contact Us," "Customer Support," or a similar title.
Speak with the sales representative and allow them to walk you through the process of adding new channels. Be sure to double-check the package you are getting and the total change to your monthly subscription fees.
