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: Does OKmarts offer volume discounts, corporate account tier pricing, or contract pricing?
A: Yes, we offer tailored B2B quotation frameworks. Procurement managers can submit a Request for Quote (RFQ) directly through the platform or contact a dedicated account manager to unlock tiered volume discounts and wholesale pricing structures.
Q: Are there any hidden fees, handling charges, or unexpected export tariffs added to the final invoice?
A: Our pricing is transparent. Line items for product costs and shipping fees are explicitly detailed at checkout. Local import duties, VAT, or regional consumption taxes are typically the responsibility of the importer of record unless a DDP (Delivered Duty Paid) arrangement is pre-negotiated.
