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?

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.

Fake/Invalid License
I purchased Microsoft Office 2021 Pro Plus Key Retail Global but unfortunately it does not work! It will not bind on your microsoft account and you will not be able to redeem the product key. Be careful on purchasing this you might not be able to use it. I tried redeeming on several methods but it can’t be redeem as it is invalid as per microsoft. setup.office.com error = Error code: TOKEN_NOT_FOUND Correlation ID: 8606c8e8-ba0a-497b-85a8-6470bb710ec3 account.microsoft.com/billing/redeem = Error code: This code wasn’t found–try re-entering it. If the code is damaged, contact the seller. I contacted them and they said it will only work on the ISO they provided, it’s pretty much the same as downloading a cracked version. THIS LICENSED CANNOT BE ACTIVATED NOR REDEEMED ON MICROSOFT
Francisco J. –
