Published prices do not include shipping charges. Shipping charges are prepaid and added to the invoice. Any estimated freight charges shown on the website or Order Confirmation e-mail are subject to change based on actual costs. Shipping estimates are meant to represent the cost of normal ground service within the 48 contiguous states for orders meeting UPS weight and dimension standards. Products considered hazardous or in need of special handling require additional shipping charges, and those charges are the responsibility of the customer.
