Top Questions from OKmarts Buyers
Q: Does OKmarts support third-party escrow services or buyer protection payment channels?
A: Yes. For buyers seeking maximum transaction security outside traditional corporate bank wires, we support payments through verified platforms like PayPal and credit card networks that offer robust buyer dispute resolution and chargeback protection frameworks in case of fulfillment default.
Q: How can a first-time international buyer verify that OKmarts is a legitimate entity and not a fraudulent website?
A: OKmarts operates under a legally registered corporate entity with verifiable business registration records, global tax compliance IDs, and physical warehouse infrastructure. We can provide corporate bank references, Dunn & Bradstreet (D-U-N-S) numbers, and customer references from established industrial firms in your region to validate our commercial legitimacy before you transfer funds.
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.
