Top Questions from OKmarts Buyers
Q: Are software licenses, firmware updates, and configuration files included with hardware like HMIs and PLCs?
A: Hardware units ship with standard factory-default firmware. For proprietary programming software or specific firmware flashes required for legacy system compatibility, buyers must consult our technical support team during procurement to confirm licensing terms.
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: What is your policy if an industrial part arrives physically damaged due to improper courier handling?
A: Buyers must inspect the outer packaging and internal items immediately upon delivery. If physical damage is discovered, document the condition with photos/videos and submit a claim to OKmarts within 48 hours of receipt so we can file an immediate report with the carrier and fast-track a replacement shipment.

Q: Can I get a refund if the price of a product drops shortly after my purchase?
A: Unfortunately, we cannot offer a refund if the price of your purchase decreases. However, within a certain period of time, we can provide you with a certain amount of discount coupons as compensation, ensuring your satisfaction. Our prices may vary due to promotions and market conditions, among other factors. We recommend making your purchase based on the current price at the time of purchase.
