I've never called for pricing here, but figured it may be worth a shot.
unless there is a considerable savings, I always try to buy locally rather than on the net as it is easier to get servicing and have problems taking care of. If you don't have a contractor tool supply, try going to a rental center and ask for pricing....they usually sell most the toos they rent.
