Basic Return Policy:
The following policy applies to products still in new condition to be returned for a refund or replacement.
- All returns must receive a Return Merchandise Authorization from our customer service team. Contact us here.
- All returns must include the original packaging (manufacturer's box, plastic bags, etc.), a valid Return Merchandise Authorization (RMA), any Manufacturing documentation (manuals, warranty cards, registration information, etc.), and the RMA number must not be written on the original manufacturer's packaging or box.
- Please write the RMA number on the label used to return the item or the return shipping box. Items received with any writing on the original packaging or box will be refused and returned to you at your cost and without credit approval.
- Unless otherwise stated below, you have 45 days from the date you receive the product to get a valid RMA from our customer service team and get your product to a shipper to return back to us. It does not have to be back in our warehouse within 45 days, but it does have to be in the possession of the shipper (along with the valid RMA). RMAs must be valid, unexpired, and issued for the product being returned. Only one RMA is issued per return. When it expires, you may no longer return your product.
- Except as provided for defective products (See Returns Policy Defective Products below), you will be responsible for all shipping charges for returns sent to our Returns Warehouse.
- There is no restocking fee for defective products (see Returns Policy for Defective Products below). However, all non-defective products are subject to a 15% restocking fee (except where prohibited by law) if returned opened or in a non-factory sealed box.
- For orders that qualified for free shipping, shipping will be deducted from the final refund if the returned items cause the order to fall below any promotional qualifications (for example, free shipping on orders over $100 and the refund causes the order to fall below $100).
- Upon our acceptance of the merchandise in like new condition in strict conformance with the basic criteria and basic returns policy, the purchase price will be credited to the credit card used for the original purchase (or, if possible, through the original payment method such as PayPal or Amazon Simple Pay).
- Please allow up to 14 days from shipment for your return to arrive at our Returns Warehouse, delivery times vary based on shipper selected. Your return will be processed within 5-7 business days (excluding Saturdays, Sundays, and holidays) after receipt of the item.
Defective Products Return Policy:
The following policy applies to defective products within 45 days of the original delivery date.
- Defective products can be returned in exchange for a replacement of the exact same product, or at the sole discretion of Motorsports Tulsa LLC. The purchase price will be credited to the credit card used for the original purchase (or, if possible, through the original payment method such as PayPal or Amazon Simple Pay). Defective products may only be returned within 45 days of the date you actually took delivery of the product.
- Once your return is processed, and is verified to meet the basic criteria above and to be defective, your replacement order will be sent to fulfillment. How quickly your replacement product ships after that depends on product availability.
- For products that we verify to be defective, we will reimburse you for your return shipping expenses, provided that your defective return must be shipped via ground shipment only. If you return your product via a faster, more expensive shipping method, you incur the expenses yourself and any request for reimbursement will be denied.
Defective Products Under Warranty Return Policy:
The following policy applies to defective products past 45 days of the original delivery date though still under warranty.
- Defective products past 45 days of delivery, but still under warranty, may be returned for an exchange only. The replacement will be the same product type and brand as the returned defective product.
- Replacement orders will be sent only after the defective product is received by our facility and it is confirmed that the Basic Return Criteria was met. The product will be verified as defective by the manufacturer.
- Customers will not be reimbursed for return shipping costs for products returned past the 45 days of the original purchase and delivery date. At the discretion of Motorsports Tulsa LLC and partsbymst.com, customers may be responsible for the cost of shipping the replacement product.
- The Manufacturer warranties only cover the replacement product. Neither MST nor the manufacturer will not include refunds for labor costs.
Returns Must Meet All Applicable Criteria
If your returned product does not match all applicable criteria listed above, it will be rejected by our Customer Service Team and returned back to you at your cost. Consequently, your RMA will be nullified, any credit request will be denied, replacement orders will not be made, and you will be charged for all shipping to and from our Warehouse that may be incurred by MST and partsbymst.com.
