Top Questions from OKmarts Buyers
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.
Q: How does OKmarts handle unexpected price fluctuations or tariff updates after an order is placed?
A: Once a Proforma Invoice is issued and payment is confirmed, your pricing is legally locked. OKmarts absorbs any subsequent raw material price spikes, supplier price adjustments, or sudden export tariff increases, guaranteeing that the price you pay at checkout is final.
Q: How does OKmarts ensure consistent communication across different global time zones?
A: We operate an international sales and support desk that covers major global operating hours. Every corporate buyer is assigned a dedicated Account Manager who coordinates cross-border communications, ensuring that urgent technical queries or logistics issues are answered regardless of the time difference.
