Overview
- Deal sites including StackSocial are running limited promotions through Oct. 4 that list Office Professional Plus 2019 for $16.97 and Office 2024 Professional Plus for $49.97.
- These purchases are perpetual licenses installed on a single Windows 10 or 11 PC and typically bind to the device hardware rather than a Microsoft account, so they are not easily transferable.
- Office 2019 no longer receives security updates after Microsoft ended support on Oct. 14, 2025, which raises long‑term security and compatibility concerns for buyers of that SKU.
- Perpetual copies do not include Microsoft 365 cloud services, AI features, ongoing feature updates, or the cross‑device portability of a subscription, so upfront savings come with functional and future‑proofing trade‑offs.
- Buyers should confirm the exact SKU, seller reputation, redemption window and compatibility before purchasing because these flash sales recur across third‑party marketplaces and activation rules and support vary.
