Walmart again 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. (Amazon charges the same for Prime members.) That's tied with our mention from April as the best price we've seen for this set. (It's also a current low by $10.) This 450-watt blender includes 40-oz. and 48-oz. pitchers, a 16-oz. chopper bowl, and storage lids.
