Kohl's offers the Ninja Master Prep Professional for $39.99. Coupon codes "SCORE" and "SUNNYDAYZ" stack to cut it to $25.49. Choose in-store pickup to dodge the $8.95 shipping fee. That's $2 under our Decmeber mention, the best deal now by $20, and the lowest price we've seen. It features 6-blade technology, an interchangeable 450-watt motor head, pulse function, and non-slip bottom. The blender comes with a 16-oz. chopper bowl, 48-oz. pitcher, and two storage lids. Deal ends June 25.
