Shipping & Returns



Once your order is placed, it will be processed immediately unless order is placed after hours, holidays and weekends. Items will usually ship same day if the order is placed before 2pm EST but some parts may be drop shipped from the manufacturer if out of stock. Although we try to have them shipped right away, we cannot guarantee same day shipment from the manufacturer on drop shipped items. Please call before placing your order to verify that your part can be shipped immediately. Pricing changes on parts listed are not guaranteed. CPP asks that customers call to check pricing as these prices change frequently and CPP is not responsible for neglected price changes. If you need a part fast, please let us know. Overnight shipping is available upon request. All order cancellations are subject to a 20% cancellation fee. CPP does not refund shipping charges if an order is cancelled unless the order has not shipped. If an item has shipped, customer is responsible for all fees associated with rerouting the shipment back to us. Customer is responsible for return shipping of items back to CPP or the manufacturer. Please understand that at times we get overwhelmed with orders and parts might not ship until the following day. We do our best to ship as fast as possible. You can send us an email and request ship date at any time before placing your order. CPP offers free shipping on orders over $150 (see details below).
