Walmart offers the Campbell Hausfeld 62-Piece Air Tool Kit, model no. 535500, for $79 with free shipping. That's tied with our May mention and the lowest total price we've seen. (It's the best deal now by $17.) It includes a 1/2" impact wrench, 3/8" air ratchet, air hammer, 3" extension bar, 1/4" swivel adapter, 1/4" coupler, and storage case.
