The Roku Streaming Stick delivers the same HD-quality movies and TV shows as Roku’s media boxes, yet it’s only the size of a thumb drive. Plug it into your HDTV’s rear HDMI port and stream content without ever seeing the Streaming Stick. And if activated by Sept. 30, 2014, Roku will give you even more entertainment options with two months free of Hulu Plus. Snag the Roku for $49.99 at Groupon Goods through August 1. Shipping is free.
