Contact DirecTV by calling their toll free number 1-888-777-8454. Choose to speak to an operator from the automated menu option and wait for a representative to answer your call. Ask the representative if he has any current deals that offer free channels to new subscribers.
Choose the package that best suits your TV watching tastes. You may be able to get a free cable package or even free basic service without a movie channel package for the first 3 to 6 months of your subscription.
Ask about equipment rental and installation fees. You might still be required to pay equipment rental fees once you begin your free subscription period. It is possible that you can install the equipment yourself, but if you do need to have someone install your satellite, you will be required to pay the installation fees.
Research comparative services like your local cable company and Dish Network to find out the type of deals they are offering and use it as a bargaining chip when you're on the phone with the DirecTV representative. If she is worried you might be seriously considering going with one of DirectTV competitors, she may be willing to pull some strings to ensure your subscription.
Be on the lookout for free movie channel weekends. Every now and again, DirecTV offers free movie channel preview weekends to help boost subscribers. You can get free HBO and Cinemax, Showtime and even Starz and Encore for the weekend, free of charge.
Avoid scams that encourage you to buy an extension or card that overrides the DirecTV signal and allows you to get free channels. This is considered stealing and could result in the company taking legal action against you.
