An order confirmation is normally sent to the email address supplied during checkout.

Most in-stock orders are prepared within 1–3 business days after payment authorization.

Address verification, payment review, peak demand, product availability, public holidays, preorders or unusually large orders may require additional processing time.

Estimated standard carrier transit within the United States is generally 5–12 business days after dispatch.

The processing period is separate from carrier transit time.

Available shipping methods and applicable shipping charges are shown at checkout before payment is submitted.

If a free-shipping offer or other shipping promotion applies, eligibility will be displayed before checkout is completed.

Orders may be fulfilled through our own operations or appropriate fulfillment partners depending on inventory availability and destination.

We do not represent that every order is dispatched from the same local warehouse.

When tracking is available, shipment information is sent to the email address provided during checkout after dispatch.

Please allow approximately 48 hours after shipping-label creation for initial carrier tracking activity to appear.

If tracking has not updated for an extended period, the order is significantly outside the expected delivery range, or a parcel marked delivered cannot be located after reasonable checks, contact service@quandbx.com with your order number.

Contact service@quandbx.com within 12 hours after purchase to request a change or cancellation.

Payment methods displayed at checkout may include major credit cards, debit cards, PayPal or other supported methods enabled for your location.

Transactions are processed in United States Dollars (USD).

Eligible products may be returned within 30 calendar days after confirmed delivery.

For preference-based returns, customers are generally responsible for return shipping.

If a damaged, defective, incorrect, incomplete or materially misdescribed item is confirmed, an appropriate replacement, refund or return solution will be provided without requiring the customer to bear the reasonable return cost caused by that issue.

No separate restocking fee is charged for approved eligible returns.

Once an approved return reaches the designated return facility, inspection is normally completed within 5 business days.

If approved after inspection, the refund is issued to the original payment method within 1–3 business days after approval.

The payment provider may require additional posting time.

Contact Customer Care as soon as reasonably possible. Where possible, we recommend contacting us within 7 days after delivery.
