Best Buy via eBay offers the open-box Beats by Dr. Dre Pill 2.0 Bluetooth Speaker in White, Black, or Red for $87.99 with free shipping. That's $97 under the lowest total price we could find for a new, factory-sealed unit, and is the best price we've seen for this model in any condition. It features Bluetooth, a built-in mic, and USB.

A 1-year warranty applies, although it's unclear who provides it.
