We only charge what it costs us to ship your package to you. Shipping rates are determined by USPS, UPS, or FedEx and are determined by the total weight of all the products being shipped, the delivery destination, and the delivery speed requested. You can always include a note in the comments box at checkout asking us to find a lower cost shipping option, and we will adjust your invoice if we can find a way to reduce the shipping. You can also place your order over the phone at 1-866-728-0070, and we can help you find the least expensive way for us to ship your package.
