 *Free shipping applies to most all orders 100.00 and over on our website. Orders with oils being shipped may have shipping either added or included. Some items have custom shipping charges added to them for orders that are under 100.00 our software doesn't recognize that or remove it automatically. We have to remove it manually from your order. Very few items have shipping added or included due to shipping charges incurred by us from our suppliers. If your order is over 100.00 and has shipping added to it when you check out please contact us so we can remove it or explain why its there.
