Top Questions from OKmarts Buyers
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.
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: 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: Are there free trial or sample giveaway activities?
A: We regularly organize free trials or sample giveaways. You can stay informed about these activities and apply to participate by following our official announcements, emails, or social media channels.
Q: How can I apply for a purchase invoice?
A: On the checkout page, you can select the option for an invoice and fill in the relevant invoice information. We will provide you with the corresponding invoice according to your request.
Q: Can I add additional items to an existing order?

If both orders are eligible for combined shipping, we will do our best to consolidate them and refund any excess shipping charges.
