Why Are Windows 11 Keys So Cheap?
Genuine Windows 11 keys can cost a fraction of the retail price for entirely legitimate reasons:
- Volume & OEM licensing: resellers buy in bulk from Microsoft partners at 70–90% off.
- Regional pricing: licenses sourced from lower-cost regions cost less but work worldwide.
- Surplus & unused licenses: businesses resell keys they never deployed.
- Online-only overhead: no physical stores means the savings reach you.
