All Sales Are Final: After 5 hours, we cannot cancel your order or issue a refund because order cancellations incur multiple transaction processing fees from Stripe and PayPal, additional shipping fees, and reverse tariff payments, which are costly and time-consuming.

If you were not at home or at your shipping address during the parcel delivery: It is not our or the supplier's fault; if the shipping/delivery company could not deliver your parcel because you, the customer, were not at home or at your delivery address on the delivery date/time, and as a result, the carrier returned your parcel to the manufacturer from where it was shipped. Please note that we do not accept excuses; you will therefore have to pay the re-shipping fee and the tariff for any re-shipment request. In such a case, we will not issue a refund.
