Newegg offers the refurbished Roku Streaming Stick, model no. 3500R, for $34.95. Apply coupon code "VISACHECKOUT" and checkout with Visa Checkout to drop the price to $31.45. With free shipping, that's $9 under our mention of a refurb from July and the lowest total price we've seen for any Roku streaming stick. (It's also $18 under the best price we could find for a new unit.) It plugs into your TV's HDMI port and streams 1080p video via WiFi. Coupon expires October 31.
A 90-day warranty applies, but it is unclear who backs it.
