I received an email from Roku regarding a sale. When I clicked on the Shop Now button, there were no prices listed for ANY device. I spent fifteen minutes attempting to find a price. No such luck. Some one at Roku has really dropped the ball.
Are you in the US? If I go to https://my.roku.com/upgrade/ or https://www.roku.com/products/players I see prices. Can you post the link you got?
