Why the price is lower than Microsoft’s

Microsoft’s list price for Windows Server 2025 Datacenter is $6,155.00. We source licenses through volume and distributor channels and sell the key without the retail box, packaging or Microsoft’s phone support, and pass the difference on. The key itself is the same genuine Microsoft key and activates on Microsoft’s servers. Read more in our FAQ.
