Impacted Shipping
Due to unstable LTL pricing, your order may require additional shipping charges. While we strive to maintain free shipping across our product line, orders shipped to limited access addresses, states in the Midwest, or states on the east coast may require additional shipping charges.
We encourage you to reach out about your order prior to payment if any of these categories apply to you. Orders placed and canceled due to additional shipping fees will still incur a cancellation/restocking fee.
Thank you for your understanding, Happy Buidling!
