Products sold by Vitabox for delivery to certain states are subject to sales tax. This will be automatically applied during checkout based on the products sold and the shipping destination. If a product is subject to sales tax in the state to which the order will be shipped, tax is calculated on the total selling price of each individual taxable product. In accordance with state tax laws, the total selling price of a product will generally include applicable product-level discounts and allocation of order-level discounts. Additionally, shipping charges may be subject to sales tax in accordance with state tax laws. The amount of tax charged on your order will depend upon many factors, including the type of product(s) purchased and destination of the shipment. Please note: Because factors can change between the time your order is placed and the time your credit card is charged, the final sales tax amount may differ from the original estimate.
