Walmart offers the refurbished Philips SoundAvia Fidelio Wireless Speaker for Apple iPhone/iPod, model no. AD7000W, for $59.98 with free shipping. That's $15 below our April mention of a new speaker and the lowest total price we could find for a refurb by $23. This 10-watt speaker features AirPlay technology and a 3.5mm audio jack.

A 90-day warranty applies, but it's unclear who supports it.
