Home Depot offers the DeWalt 20-volt Max 2-Tool Combo Kit, model no. DCK280C2, for $199 with free shipping. (Amazon charges the same.) That's the lowest total price we could find by $30. It features a 1/4" impact driver, a 1/2" drill/driver, two lithium-ion batteries, charger, and carry bag.
A close price: Sears has it for a buck more.
