The regular prices might be a little inflated all over the world (I've seen that happen), but the sale on the Panasonic 12 V (3.5 amp hour) cordless drill and impact driver looks like a great deal to me. You can get twice as many (four) batteries and an extra charger FWIW for less than the cheapest price for the combination drill/impact kit. Another way of looking at it... you get four batteries, two chargers, a drill/driver, and an impact driver, for less than the cost of four batteries. Difficult to believe IMO.
