Why is it significantly cheaper than purchasing from Microsoft?

Superlicensekey refurbishes a substantial number of ex-corporate systems, many of which have Office installed. Since Office 2021 operates on a perpetual license, Superlicensekey owns both the device and the licenses on the system after taking control of systems for refurbishment. By owning the license, Superlicensekey can deactivate it and obtain a new one through Microsoft’s licensing agreement, allowing us to offer these licenses at a reduced price. Rest assured, the license is exclusively issued to you, legally valid, and remains yours for a lifetime.

Office 2021 is always a perpetual license, unlike Microsoft 365/Office 365, which requires a monthly or yearly payment. Office 2021, similar to Office 365, entails a one-time payment, with no additional costs after purchasing the license from us.
