As soon as we receive your order, we automatically reach out to our suppliers to confirm that it is in stock and available for immediate shipment. If your item is on backorder or unavailable, we will void the pre-authorization and reach out to you via e-mail.

With that being said, if a customer decides to cancel an order due to a shipment not arriving in the estimated time frame, customer is responsible for all associated shipping charges, fees, warehouse storage costs, and any other fees associated with the order. Any customer that files a chargeback for delays in shipping will be held criminally liable for theft. No Exceptions Apply.

These units are custom made to your specification or created once you order. Once you place your order they start building your unit. Your warranty will guarantee you a fully functional and operational product. If it is not clear whether your order is custom or made to order, please message or call us.
All sales are final for Custom made and Made to order products.
Refunds and Returns.
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.
Not all orders are available for return once they have shipped. We order our products directly from the manufacturer. Therefore, if the manufacturer will not permit us to return a product, we cannot offer you a return. This often varies on a case-by-case basis; please reach out to us if you would like specific information on your brand and/or product.
Due to drastically increasing LTL/freight shipping costs, any outright returns will incur a 25% cancellation fee + return shipping costs. 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.
Customers have 30 days from the date they received the item to initiate a return, however, please check the specific return policy for the brand of product you are purchasing as the brand specific return policy on the product page overrides this general return policy of 30 days.
