However, this is a one-time fee and the membership will give you access to exclusive online member pricing for one year. The lowest price we found for this pressure washer at any other store was $116.99. It comes with a 20' hose, a spray wand, a soft bristle wash brush, and a foam nozzle. Sales tax is charged in most states.
