Top Questions from OKmarts Buyers
Q: What financial protections do I have if the shipped goods do not match the ordered part numbers or technical specifications?
A: OKmarts operates under a strict Order Accuracy Guarantee. If the part numbers delivered do not match your approved Proforma Invoice or Purchase Order due to our fulfillment error, we will issue a full refund or expedite a replacement shipment immediately, covering all return international freight charges.
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: 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.
