    When will I know my order has shipped?

    An email with tracking information will be sent to the customer within 24 hours of the order being shipped to the e-mail address you provided when checking out. If you have multiple items on your order, you may receive more than one tracking number as the items may ship separately. If you have not received tracking info within 3 days after the lead time posted on the product page, please contact us at info@royalfirepits.com.

    When will my order ship?

    As soon as you place your order, you will receive an order confirmation e-mail. This means that we have received your order in our system and pre-authorized your credit card for the purchase. As soon as we receive your order, we will process and submit the order with our suppliers for shipment within 24 hours. If your item is on backorder, we will void the pre-authorization and reach out to you via e-mail.

    Shipping Times

    We promise to do our best to get your order to you as soon as possible. All orders are shipped within the lead time posted on the product page. This is located on the product page right below the "Add To Cart" button. These times are based upon what our supplier and freight companies tell us, and those estimated shipping times may change or vary without notice (Due to supply chain issues, manufacturers delayed because of the mills, overwhelming demand on shipping, and so on).

    Order delays have proven to be unavoidable and outside of Royal Fire Pits control. While this might be frustrating, we ask you to please be patient and understanding with us in these tough times. We thank you for your business and appreciate your patience.

    Returns

    We have a 30-day return policy, which means you have 30 days after receiving your item to request for a full refund.

    If you are replacing the product with something else, we may be able to help you cover some of the costs depending on the product.

    If you need to exchange your product, you may do so. You, as the customer, are responsible for any shipping costs throughout any returns and exchange processes.
