Overview
This Return Policy applies to auto parts purchased from Once Management LLC. We want you to receive the right part in the condition described. Please read this policy before ordering and contact us before returning anything.
Return eligibility
You may request a return within [30] days of delivery if:
- The part does not match the description on your invoice, or
- The part is defective on arrival, or
- We shipped a part that does not fit the vehicle and VIN you provided.
To qualify, the part must be uninstalled, unmodified, and returned with all components, in its original condition, with any paint or identification markings intact.
Items not eligible
- Parts that have been installed, disassembled, modified, painted or damaged after delivery.
- Electrical parts and modules (such as ECUs) once installed or programmed.
- Parts ordered using incorrect vehicle information supplied by the customer.
- Special-order items marked "final sale" on the quote or invoice.
- Damage caused by improper installation, overheating, lack of fluids, or failure to replace required components.
How to start a return
- Contact us at info@oncemanagementllc.com or (816) 799-8758 with your order number and the reason for return.
- We'll review the request and, if approved, issue a Return Merchandise Authorization (RMA) number and instructions.
- Package and ship the part as instructed. Returns without an RMA cannot be accepted.
Refunds
Once we receive and inspect the returned part, approved refunds are issued to the original payment method, typically within [5–10] business days. Original shipping charges are non-refundable unless the return is due to our error.
Returns for reasons other than our error (for example, no longer needed) may be subject to a restocking fee of up to [20]%, and the customer is responsible for return freight. Where we made an error, we cover return shipping.
Limited parts warranty
Eligible used engines and transmissions include a limited parts warranty of [warranty period] from the delivery date, as stated on your invoice. The warranty covers internal mechanical failure of the part itself and provides, at our option, a replacement part or a refund of the part price.
The warranty does not cover labor, towing, rental vehicles, fluids, gaskets, seals, sensors, attachments, or consequential costs. It is void if the part is installed incorrectly, overheated, run without proper fluids, used for racing or commercial modification, or if required items (for example timing belt, water pump, thermostat, transmission cooler flush) were not replaced at installation. Professional installation receipts may be required for claims.
Shipping damage
Inspect your shipment before signing the delivery receipt. Note any visible damage on the carrier's paperwork and contact us within 48 hours with photos so we can file a claim and arrange a solution.
Freight services
Freight transportation services are not "returnable." Loss or damage on freight shipments is handled through the claims process described in our Terms & Conditions. Cancellations of freight orders after dispatch may incur truck-ordered-not-used (TONU) or similar charges.
