                                Some items may be special order specifically for the customer’s vehicle. These items generally require a deposit or paid in full. Once this deposit amount is notified to the customer and they agree to order the special order item, the deposit becomes non-refundable. These special order items cannot be returned or resold. Cancellations are not allowed on special order parts.

                                ** All cancellations that are requested that are NOT due to items not being in stock or delayed by the manufacturer are subject to a 5% processing fee. When you place an order with us we pay credit card fees that are NOT returned back to us. We will absorb these fees if we do not have the item in stock OR if you agree to the original ETA and that ETA is NOT met. If you decide to cancel for any other reason you will not receive this 5% fee back
