Microsoft's push to get Windows and Office users to buy Microsoft 365 subscriptions can be irritating, but to the company's credit, it's one of the few that has continued to sell buy-once, use-forever versions of its flagship software after launching a subscription model.

For Windows users, Microsoft Office Pro 2021 is available for just $39 instead of $219 which is an incredible 81% discount. Mac users can also take advantage of the Home & Business 2021 version for only $69 instead of $249, representing a 72% savings just ahead of Prime Day. You can also get the Office Professional Plus 2019 version for $25 here.
