Walmart offers the Ninja Master Prep Profesional 48-oz. Food Processor in Black, model no. QB1004, for $39.88. Opt for in-store pickup to avoid the $4.97 shipping charge. That's tied with our mention from July as the best price we've seen for this set. (It's also a current low by $6.) This 450-watt blender includes 40-oz. and 48-oz. pitchers, a 16-oz. chopper bowl, and storage lids.
Of note: Amazon charges the same for its Prime members only with free shipping. Home Depot and Jet also offer it for the same with free shipping.
