Shipping is free on all US orders over $150, and less than 3 pounds, via USPS Ground or UPS Ground only. Even when we receive an order and shipping is calculated, we will manually remove the shipping charge if the products you ordered amount to over $150 and the shipping desired meets the criteria (i.e., UPS Ground, USPS Ground). This applies only to US orders and does not apply to overseas orders or special orders or special delivery of packages. It does not apply to next day, second day, or certified delivery, nor does it apply to FedEx. If another carrier other than USPS Ground or UPS Ground is desired, the customer will be charged the full cost of that carrier.
