Shipping Responsibility Disclaimer

Once a package is marked as "Delivered" by the carrier, we are no longer responsible for its whereabouts unless you specifically requested a signature requirement at checkout. If no signature is requested and the package goes missing after delivery, we cannot be held liable for the loss. Additionally, any delivery issues must be reported to us within 12 hours of the marked delivery time. Failure to notify us within this timeframe may result in a forfeiture of claims, as delayed reporting significantly reduces the chances of locating a misdelivered package. If you would like to add insurance to your shipment to protect against potential loss or theft, please inform us before your order ships. Insurance is not included by default.

SHIPPING COST DISCLAIMER

Shipping can be very complicated, especially with LTL Freight items, and it can be challenging to always quote the exact shipping price with complete accuracy. We do not make money from shipping and only pass along the actual shipping cost charged by the carrier.

If the shipping cost we quoted or provided is less than the actual amount charged by the carrier, we reserve the right to not honor the sale at that shipping price and may cancel the order if necessary. However, before any order is canceled, you will be given the opportunity to pay any additional shipping charges if you choose to do so.
