All orders are digitally processed and submitted to the warehouse soon after an order is confirmed. Therefore, the window to cancel an order is limited. All orders should be cancelled before you receive the Invoice - Payment accepted Email. No orders can be cancelled after payment is has been confirmed, because the order is going to be immediately processed for shipment by our company. All orders on our website www.asautoparts.com which are placed from Friday after 5PM EST to Monday 9AM EST cannot be cancelled, because they are processed over the past weekend for shipment.
