The S/H charges for Power Sprayers are listed as the last page link below. S/H charges for PVC pipes, Lead, Brass Quick Connects, and other fittings will be added after you place your order. Plastic pipes weigh only a few ounces, but brass can become several pounds very quickly. Therefore, we decided it would be best to simply wait and see what each shopper orders first and then we could give a better shipping cost. Some states do charge a tax in their state. They are Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Missouri, Mississippi and S. Carolina.
