Top Questions from OKmarts Buyers
Q: How can I verify that a product on OKmarts is brand new and not "New Old Stock" (NOS) with degraded internal components?
A: Our warehouse management system strictly tracks manufacturing date codes, especially for sensitive components like VFD electrolytic capacitors or rubber seals. We explicitly state product conditions on the listing and can provide batch date codes prior to shipment for critical applications.
Q: Does OKmarts support third-party escrow services or buyer protection payment channels?
A: Yes. For buyers seeking maximum transaction security outside traditional corporate bank wires, we support payments through verified platforms like PayPal and credit card networks that offer robust buyer dispute resolution and chargeback protection frameworks in case of fulfillment default.
Q: Can I request a live video inspection of my specific order items before they leave the OKmarts facility?
A: Yes. To maximize peace of mind for high-value or critical orders, buyers can request a "Pre-Shipment Video Verification." Our warehouse team will film the unboxing, display the original manufacturer seals, show matching serial numbers, and verify the physical condition of the components in real-time or via a high-definition video link.
