A:Answer You can just plug a Roku in and once registered with Roku you can watch all the free content available. Roku has their own free channel with movies, tv series, etc that are available to watch completely free. There are subscription based services like Sling, YouTube TV, Hulu and such that do have a subscription cost per month. You can save a billing credit card in Roku and it will bill your monthly subscriptions for you. Just remember to cancel through Roku when the time comes. There are a lot of free channels you can search for and save on Roku. A few good suggestions are Pluto, Tubi, Crackle. These are ad supported channels so expect a few ad breaks every so often. If you are looking for a subscription service that offers a lot of channels cheaply go with Philo, they are around $20 a month have close to 60 channels like Hallmark, AMC, Food Network, Paramount, Lifetime, etc. The only problem with Philo is they don’t have ESPN and local channels. You can buy an antenna and pick up local channels that way if you live close to a large city. Hopefully that answers all your questions. Happy streaming !!!
