We are required to charge sales taxes for orders shipped to U.S. states where sales taxes are applicable. Sales taxes are determined by the state into which an order is shipped, based on the current tax rates. Our Website will calculate an estimated sales tax for your purchase, based on the state into which the order is shipped. Your exact sales tax will be included with your order confirmation email. In some states, shipping charges may also be subject to a state tax. Tax will be refunded for returned items.
