No, probably not. Our distribution center is fully automated, once an order is placed it's immediately processed by the fulfillment center and is picked electronically for shipment. Once that process is underway we are unable to cancel the shipment. It's the customers responsibility to ensure the parts ordered are correct. Customers are given a confirmation page to view showing the list of parts before they complete the checkout process. If you need to cancel your order please email us immediately and include your name, order number, phone number and reason for canceling. These requests must be made via email. If by chance the order has not shipped it can be canceled without issue, minus a $30 cancellation fee or 10% for orders over $300. Keep in mind, just because you haven't received tracking doesn't mean the order hasn't shipped. Our system typically emails tracking numbers at the close of business each day. We are very efficient in processing orders, most shipments are fully processed within just a few minutes after an order is placed. If the order has shipped the customer can go through the standard return procedure to receive a refund. Customers will need to receive an RMA number via email so the return can be processed. For more information about the terms and conditions which will govern your return please refer to our return policy.
