Wrong part/size or change of mind: a 20% return processing fee applies, plus applicable shipping costs.
Original shipping is non-refundable. For orders shipped free, the actual outbound shipping cost is deducted from the refund. Return shipping is prepaid by the customer.
After payment capture, cancellations and refunds generally incur a 5% processing fee, except for our error, confirmed defects or confirmed carrier loss. The 5% and 20% fees do not stack; only the greater applicable fee applies. Store credit waives the 5% fee, but applicable return fees remain.

For defective items, contact us for help with the manufacturer's warranty process. The manufacturer decides the claim.
