newegg.com offers the refurbished Magnavox WiFi Blu-ray Disc Player, model no. MBP5320, for $39.99. This $20 mail-in rebate drops it to $19.99. With free shipping, that's the lowest total price we've seen for any WiFi Blu-ray player. (It's also $20 under the price of a refurb elsewhere.) It features WiFi, HDMI output, USB, and support for streaming apps such as Netflix, YouTube, and Vudu. Rebate ends July 7.
A 90-day warranty applies, although it's unclear who backs it.
