Sears offers the Kenmore 0.7-Cubic Foot Countertop Microwave Oven, model no. 69079, for $49.99. Choose free in-store pickup to dodge the $20.04 shipping fee. That's tied with our mention from March and the least expensive Kenmore microwave we've seen. It features 10 power levels, LED display, auto defrost, child lock, and more.
