Buy Office cheap — one-time purchase or Microsoft 365

Buy genuine Microsoft Office for less and pick the right model the first time. Below you compare a one-time Office purchase against a Microsoft 365 subscription, see which edition fits Windows or Mac, and get an instant key with invoice and activation help.

One-time purchase or Microsoft 365 subscription?

A one-time Office licence (Office 2024 or 2021) is a perpetual purchase: pay once, use it for years with no monthly fee. Microsoft 365 is a subscription that adds cloud storage, always-the-latest features and multi-device cover. If you keep software for years and do not need the cloud extras, the one-time purchase usually wins on cost.

Which Office edition do you need?

• Office Home & Business includes the classic apps plus Outlook — ideal for most home and freelance use.
• Office Professional Plus adds the full app set for power users and businesses.
• Office for Mac gives you the same perpetual model on macOS.
• Microsoft 365 is the choice if you want OneDrive storage and continuous feature updates.
