Newegg offers the refurbished Roku Streaming Stick, model no. 3500R, for $39.95. Coupon code "EMCWPGP77" cuts it to $34.95. With free shipping, that's the lowest total price we could find for a new unit by $14, although we saw it four weeks ago for $4 less. It plugs into your TV's HDMI port and streams 1080p video via WiFi. Coupon expires November 1.
A 90-day warranty applies, but it's unclear who backs it.
