USA World Sales via eBay offers the refurbished Ninja Professional Blender with Single-Serve Cups, model no. BL660, for $79.99 with free shipping. That's $26 below the lowest total price we could find for a new unit, although it was $3 less after a gift card in November. This 1,000-watt blender features a 72-oz. capacity, single-serve function, and two 16-oz. cups with to-go lids.
