Roku offers a wide variety of channels that may be added free of charge. Roku also provides channels for purchase. Some channel providers may require additional fees or requirements to access a channel. A channel provider may require you have an account with them, pay a subscription or a pay per use fee to access the channel. This is true for channels that are free or are purchased from the Roku Channel Store.
Channel prices and additional requirements set forth by the channel provider can be viewed on the channel details screen in the Roku Channel Store.
