Top Questions from OKmarts Buyers
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.
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: 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.
