Top Questions from OKmarts Buyers
Q: Are the products listed on OKmarts sourced from the gray market or unauthorized liquidation stock?
A: No. Unlike surplus liquidation brokers who sell unpredictable, unvetted excess inventory, OKmarts builds strategic partnerships directly with active factory supply chains and authorized distribution channels. This ensures that every component is fully traceable, factory-fresh, and covered by standard manufacturer liability frameworks.
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: What happens if an item is damaged in production due to an installation error by our technicians? Will OKmarts help?
A: While standard warranties do not cover user-inflicted installation damage, we support your recovery velocity. In emergency situations where a commissioned part is accidentally fried or structurally damaged, we offer an expedited "Rapid Replacement" service, prioritizing your emergency order at a discounted technical assistance rate to minimize factory downtime.
