Order processing begins after checkout requirements and payment confirmation have been completed. Preparation time may vary depending on inventory, order volume, product type and warehouse operations.

If an exceptional issue affects fulfillment, we may contact you using the details provided with the order.

Shipping is available only to destinations supported by the live checkout. Eligibility can vary by product, delivery address, carrier availability and applicable restrictions.

Some electronics, batteries or other regulated items may be subject to additional transport restrictions.

For eligible U.S. orders, Standard Shipping is $2.99 USD and Express Shipping is $5.99 USD when those services are available at checkout.

The final shipping charge, if any, is displayed before you submit payment. Other destinations may have different rates or may not be available.

For eligible U.S. orders, the estimated delivery window is 2–7 days after order confirmation under normal conditions.

This is an estimate rather than a guaranteed arrival date. Inventory constraints, holidays, severe weather, remote locations, customs procedures or carrier disruptions may affect timing.

When tracking is available, a tracking number or status link may be provided by email or through another order notification.

Tracking can take time to become active after a label is created. Carrier scans and transit updates are controlled by the carrier.

Review your delivery address carefully before placing the order. If you notice an error, contact customer care immediately.

We cannot guarantee that an address can be changed after the order has entered processing or has been dispatched.

Delivery to PO boxes, military addresses or other special destinations depends on the shipping service available at checkout. Please confirm eligibility before ordering.

Unexpected delays can be caused by carrier backlogs, weather, transport interruptions, public holidays, customs or peak shopping periods.

If your shipment is significantly delayed or tracking remains inactive for an unusual period, contact service@qsfdsz.com with your order number.

If tracking indicates a delivery problem or a shipment appears lost, contact customer support. We may ask you to verify the delivery address and cooperate with any carrier investigation before a resolution is issued.

If tracking shows delivered but you cannot locate the parcel, check the delivery area, household members, reception or concierge locations and any carrier delivery notes.

If the package remains missing, contact customer care so we can review the next available steps.

If the outer package or product arrives damaged, or an item is missing, contact us promptly and provide your order number plus clear photos where appropriate.

Keep the packaging until the issue has been reviewed if it is safe and practical to do so.

International delivery is available only where shown at checkout. Customs procedures, import rules, local taxes or duties may apply depending on destination and order type.

Any amount not collected by the store at checkout may be the responsibility of the recipient where permitted by law.
