Groupon offers the refurbished Jawbone Big Jambox Wireless Bluetooth Speaker in five colors (Platinum Grey pictured), model no. J2011, for $69.99 with free shipping. That's $10 under our mention of a refurb from a year ago and the lowest total price we've seen in any condition. (It's also $50 less than you'd pay for a refurb today.) Features include a microphone, 3.5mm jack, microUSB port, 33-foot wireless range, and up to 10 hours of playback on a single charge. Deal ends today.

A 90-day warranty is provided, but it's unclear who backs it.

Update: Even better, apply coupon code "SALE3" to cut the price further to $62.99.
