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.
