Newegg offers the refurbished Roku Streaming Stick, model no. 3500R, for $34.95 with free shipping. That's tied with last month's mention and the lowest total price we could find for a refurb by $5. It plugs into your TV's HDMI port and streams 1080p video via WiFi. Deal ends February 26.
A 90-day warranty applies, although it's unclear who backs it.
