Sales tax is only required for orders shipping into states where we have or may have nexus for state tax purposes under applicable laws. Therefore all orders shipping into California, New Jersey, New York and Tennessee will be charged applicable sales tax according to your area's tax rate. Please note that the sales tax for New Jersey, New York and Tennessee orders is calculated based upon the total price of the order, including shipping and handling. The tax imposed by these states on shipping and handling is part of the state sales tax, not a separate tax.
