Purchases are generally processed in United States Dollars (USD), unless another currency is specifically displayed during checkout. Your bank or payment provider may apply its own currency conversion rate or international transaction fees.

Available payment methods are displayed at checkout. Depending on eligibility and location, options may include PayPal and supported credit or debit cards.

If PayPal offers guest checkout for your transaction, you may be able to use an eligible debit or credit card without signing into a PayPal account. Availability is determined by PayPal.

Contact us as soon as possible. Cancellation or address-change requests submitted within 12 hours of purchase will be reviewed whenever operationally possible. Once an order has entered fulfillment or has been dispatched, changes may no longer be possible.

Estimated transit times after dispatch are generally:

United States: 10–15 business days
Canada / United Kingdom / Australia: 11–16 business days

These are estimates rather than guaranteed arrival dates.

Yes. Once your order has been dispatched, available tracking information will normally be sent to the email address used during checkout. Carrier tracking may take approximately 1–3 business days to display its first update.

A temporary pause in tracking does not always mean the package has stopped moving. If tracking remains inactive for an extended period or you believe the shipment may be lost, contact service@derlune.com with your order number.

Please check around the delivery location and with household members or building staff where appropriate. If the package still cannot be located, contact our support team. A “Delivered” tracking status does not automatically prevent us from reviewing your delivery concern.

Eligible products may be returned within 180 calendar days after delivery, subject to the conditions stated in our Return & Refund Policy.

For a standard preference-based return, the product should generally be unused or in substantially the same condition in which it was received, with original packaging and supplied accessories where reasonably available.

Contact service@derlune.com before sending your item. Please include your order number, the product you wish to return, the reason for the request, and photos or video where relevant.

No. Please do not automatically send returns to our business registration address. Once your request is approved, our support team will provide the correct return warehouse address and return instructions.

For preference-based returns, such as changing your mind, the customer is generally responsible for return shipping. If the product arrives damaged, defective, incorrect, incomplete, or materially different from its description, we will provide an appropriate solution without requiring the customer to bear reasonable return costs caused by our error.

Once an authorized return has been received and inspected, approved refunds are generally issued to the original payment method within 5–10 business days. Your bank or payment provider may require additional time to display the refund.

Contact us with your order number and clear photos or video where appropriate. Depending on the circumstances, the resolution may include a replacement, refund, return arrangement, or another suitable solution.
