Frequently asked questions
How do we keep our prices so low?
Digital fulfillment and volume sourcing let NDWS Market price many products below typical retail levels.
Are our codes/keys real?
Yes. NDWS Market products are sold for legitimate activation and standard digital delivery.
How long does it take to get my order?
Most orders are delivered within minutes, although verification or payment checks can occasionally add some delay.
Do we ship by post?
Software keys and digital products are delivered electronically. Physical shipping only applies when a listing clearly includes hardware.
How can I download/view my code/key?
You receive the key and any included instructions by email after checkout, so you can access the product details digitally.
Are there subscription fees for your product keys?
No recurring subscription is added unless the product itself is specifically sold as a subscription-based license.
Can I redeem/activate my product key later?
Usually yes, but activating sooner is still the safer option so you can confirm everything is working while the order is fresh.
I do not know how to activate my product key.
Use the included setup guidance first. If anything is unclear, contact support and we will help you complete the activation.

Decepcionado, compre licencia Windows 10 y la que me mandaron estaba en uso, aunque hay que decir que me facilitaron otra.
Posteriormente compre licencia Office 2021, esta licencia no se activa y lo que es peor no tengo soporte, no responden a los correos, con lo cual he perdido el dinero y la esperanza. Bajo mi experiencia no lo recomiendo
