To make a purchase from the Roku Channel Store you’ll need a valid payment method associated with your Roku account. Accepted payment methods are either a credit card (MasterCard, Visa, American Express or Discover) or PayPal.
You can place a payment method on file by logging in to your Roku account and clicking “Add a payment method for Channel Store purchases” under “Payment Method”.
