Order Acceptance

GCP Tuning reserves the right to cancel or refuse any order at any time without notice. Some situations that may result in the cancellation of an order include limitations on quantities available for purchase, inaccuracies, errors in product or pricing information, or problems that are identified by our Credit and Fraud Prevention Department. In some cases we must contact you to obtain and verify additional information before accepting an order. If your order is canceled for any reason or additional information is required, GCP Tuning may contact you by phone and/or email. Please be sure that you verify your contact information on the order as it must be valid to be accepted. If the contact information is fictitious or invalid we reserve the right to cancel an order.

If this is your first order with GCP Tuning, it is required that your first orders be shipped to the billing address associated with your Credit Card. Providing mismatched addresses, or an address that is different from what is listed on your card/bank statement may result in delays during the order review process.

Under most circumstances, your credit card will be authorized for an amount less than the order total when your order is submitted. This authorization will be voided once your order is being processed for shipment in the warehouse, at which time your credit card will be charged for the full amount of the sale transaction. If you decide to cancel an order that has an authorized payment status, our Billing Department will void this authorization. It is usually removed from the account within 5-7 business days.

Special order and/or No Cancel-No Return items will require full non-refundable payment before the order is placed with our suppliers. Under no circumstances will this value be refundable in the event that the order does not ship due to customer cancellation or refusal at the time of delivery.

Orders containing any part marked as "Direct Ship", or any order with a status of "Direct Ship", cannot be cancelled once placed. These orders have open PO's with the vendors fulfilling the orders, and as such, cancellations cannot be processed. Our staff would be more than happy to provide RMA for any parts that are no longer needed, once they have been delivered.

International Orders

Please be advised that your country may impose duty fees, or other taxes based on the product origin and/or value. These fees and taxes are based on your country's import policy, and may be imposed in addition to the purchase price and shipping/handling fees collected by us prior to shipment. All such fees and taxes are the sole responsibility of the recipient and any and all charges incurred by GCP Tuning will be charged to the customer. GCP Tuning is not responsible for such fees/taxes on returned items. If you are concerned about possible additional charges, please contact your local Import/Customs authority for more information. All charges, sales, returns, and exchanges will be calculated in US dollars. GCP Tuning is not responsible for fluctuations in currency value.

International customers are responsible for understanding their country's international buying laws, and should be aware that all international purchases are subject to additional brokerage, duty or tax fees that are collected at the time of delivery unless otherwise noted by GCP Tuning. GCP Tuning is not responsible for these charges as we have no affiliation with tax systems set forth by international countries. If the consignee/receiver refuses to pay these additional charges at the time of delivery, GCP Tuning will instruct the shipping carrier to abandon the package. Abandoned packages are destroyed at the shipping warehouse at your local pick up facility. GCP Tuning will not be held responsible for any abandoned packages due to these circumstances.

Some products offered by GCP Tuning may have a core charge deposit that is required during the initial purchase. In some cases, GCP Tuning is unaware of a core charge until after a product has been ordered. If a core charge is required after the product has been ordered, GCP Tuning may contact the customer to inform them of the core charge. Core charges are usually combined with the initial cost of the product purchased and you may qualify for a core refund if the product is returned. Please contact a Customer Service Representative to obtain an RMA number.

In order to receive core credit, the product must be in rebuild-able condition without any damaged, structural harm or missing items. The core must be returned to GCP Tuning in the original OEM package in which the original product was sent.

GCP Tuning inspects all products that are returned for core credit and reserves the right to determine if the core returned qualifies for core credit. Cores that are not returned in the original packaging will not qualify for core credit. GCP Tuning does not accept junkyard cores. If the return does not meet these requirements, the items will be returned or discarded at your discretion. If the core is denied for core credit, the customer is responsible for the cost of having the item returned.

Please allow an ample amount of time for core charges to be processed, as GCP Tuning needs to inspect all parts before a refund is granted. Return shipping for core charge refund is the sole responsibility of the buyer and all cores must be returned within thirty days of original purchase. Shipping Charges are non-refundable. See the Return Process below.
