This Craftsman 12-gal 5.0 peak hp Wet/Dry Vac, originally $79.99, drops from $58.30 to $52.47 when you add it to your cart at Sears.com. Then add code SEARS2013 to drop the price to $47.47, the lowest we could find on a 12-gal vac. To avoid a $19.56 shipping charge, either pick it up at your local store, or add this crevice tool ($54.66 order total) or this dust brush ($55.56 order total), and your order ships free. (We don't completely understand the math either.) Sales tax is charged in most states.
